QMSS provides students with a basis in quantitative skills for social science research through its core curriculum, with the flexibility to engage in interdisciplinary pursuits through their elective selections. Students can select these classes from the elective offerings by QMSS, or draw from the wider university through cross-registration in the many departments across Columbia that QMSS has developed strong relationships with over the years. Below are descriptions of the courses offered by QMSS as well as a selection of courses around the university that may be of interest. Students are advised to work with the program to determine a course of study that suits goals for program design as well as to receive guidance on their options for study throughout the university.
Core QMSS Courses
The five courses below or their equivalents are completed by ALL QMSS Students.
QMSS Theory and Methodology (QMSS GR5010)
This interdisciplinary course, taken in the fall semester, is a comprehensive introduction to quantitative research in the social sciences. The course focuses on foundational ideas of social science research, including strengths and weaknesses of different research designs, interpretation of data drawn from contemporary and historical contexts, and strategies for evaluating evidence. The majority of the course is comprised of two-week units examining particular research designs, with a set of scholarly articles that utilize that design. Topics include: the “science” of social science and the role of statistical models, causality and causal inference, concepts and measurement, understanding human decision making, randomization and experimental methods, observation and quasi-experimentation, sampling, survey research, and working with archival data.

QMSS Thesis (GR5999)
All students must complete an MA thesis, which involves original statistical analysis, under the supervision of the student's advisor and the QMSS program director. Students should register for this course in the last semester of their program
QMSS Students typically take between 4 and 6 elective courses. Any 4000-level or above course offered by QMSS, Computer Science, Economics, Statistics, Political Science, Sociology, Mathematics, or SIPA will satisty one of these requirements. 4000-level courses outside these departments MAY satisfy an elective requirment but require approval by the Director of QMSS.
Each focus has its own guidelines regarding elective distribution, so be sure to read your Degree Requirements worksheet carefully.
Some popular elective courses are listed below. Be aware that course listings are always subject to change. You should always check in the the Columbia Directory of Classes for the most up-to-date information.
Traditional Track QMSS Students must take TWO Research Methods Electives. We Strongly encourage they fulfill this requirement through QMSS department electives.
Time Series, Panel Data, and Forecasting (QMSS GR5016)
This course will introduce students to the main concepts and methods behind regression analysis of temporal processes and highlight the benefits and limitations of using temporally ordered data. Students study the complementary areas of time series data and longitudinal (or panel) data. There are no formal prerequisites for the course, but a solid understanding of the mechanics and interpretation of OLS regression will be assumed (we will briefly review it at the beginning of the course). Topics to be covered include regression with panel data, probit and logit regression of pooled cross-sectional data, difference-in-difference models, time series regression, dynamic causal effects, vector autoregressions, cointegration, and GARCH models. Statistical computing will be carried out in R.

Introduction to Missing Data (QMSS GR5059)
The goal of this course is to provide students with a basic knowledge of the potential implications of missing data for their data analyses as well as potential solutions. Students will looks at different types of mechanisms that can generate missing data. This will lay the groundwork for discussions of what types of missing data scenarios can be accommodated by each missing data method discussed subsequently. Finally, students will learn how to deal with missing data in Stata. More advanced techniques will be covered in a course later on, using R and Stan. Any QMSS student is presumed to have sufficient background. Any non-QMSS students interested in taking this course should have sufficient background in regression modeling of discrete variables. Topics to be covered are probability theory, endogenous selection, mechanisms of missing data, single imputation methods, multiple imputation methods, multivariate normal imputation, conditional imputation, and post-imputation diagnostics.
Social Network Analysis (QMSS GR5062)
The course is designed to teach students the foundations of network analysis including how to manipulate, analyze and visualize network data themselves using statistical software. We will focus on using the statistical program R for most of the work. Topics will include measures of network size, density, and tie strength, measures of network diversity, sampling issues, making ego-nets from whole networks, distance, dyads, homophily, balance and transitivity, structural holes, brokerage, measures of centrality (degree, betweenness, closeness, eigenvector, beta/Bonacich), statistical inference using network data, community detection, affiliation/bipartite networks, clustering and small worlds; positions, roles and equivalence; visualization, simulation, and network evolution over time.
Data Visualization (QMSS GR5063)
Bayesian Statistics for the Social Sciences (QMSS GR5065)
An introduction to Bayesian statistical methods with applications to the social sciences. Considerable emphasis will be placed on regression modeling and model checking. The primary software used will be Stan, which students do not need to be familiar with in advance. Student in the course will access the Stan library via R, so some experience with R would be helpful but not required. Any QMSS student is presumed to have sufficient background. Any non-QMSS students interested in taking this course should have a comparable background to a QMSS student in basic probability. Topics to be covered are a review of calculus and probability, Bayesian principles, prediction and model checking, linear regression models, Bayesian data collection, Bayesian calculations, Stan, the BUGS language and JAGS, hierarchical linear models, nonlinear regression models, missing data, stochastic processes, and decision theory.
Experimentation in the Social Sciences (QMSS GR5068)
The course is designed to provide students with a basic introduction to the use of experimental methods in political and social sciences. Students will be exposed to methodological, theoretical and practical aspects of experimentation. No prior knowledge of experimental methods is required. Topics to be covered are causal inference randomization and validity; reporting experimental research; experimental design and analysis; ethics, human subjects research and the IRB; laboratory experiments; survey experiments; field experiments; quasi-experimentation, natural experiments and regression discontinuity designs; and integrating experimental research.
Applied Data Science for Social Science (QMSS GR5069)
In his now classic Venn diagram, Drew Conway described Data Science as sitting at the intersection between good hacking skills, math and statistics knowledge, and substantive expertise. By training, social scientists possess a IUD combination of all three, but also bring an additional layer to the mix. We have acquired slightly divergent training, skills and expertise tailored to understand human behavior and to explain why things happen the way they do. Social scientists are, thus, a particular kind of data scientist. This course is not intended to teach you how to code, create visualizations, or estimate models. It presumes you have learned that in other classes. This course is intended to take you to the next level in becoming a data scientist.
GIS Spatial Analysis (QMSS GR5070)
This course introduces students to basic spatial analytic skills. It covers introductory concepts and tools in Geographic Information Systems (GIS) and database management. As well, the course introduces students to the process of developing and writing an original spatial research project. Topics to be covered include: social theories involving space, place and reflexive relationships; social demography concepts and databases; visualizing social data using geographic information systems; exploratory spatial data analysis of social data and spatially weighted regression models, spatial regression models of social data, and space-time models. Use of open-source software (primarily the R software package) will be taught as well.
Advanced GIS Spatial Analysis (QMSS GR5071)
This course builds upon foundational spatial analysis concepts and skills built in the introductory GIS course through the application of advanced spatial statistical modeling tools. Topics covered include 1) Graphical and quantitative description of spatial data, 2) Kriging, block kriging and cokriging, 3) Common variogram models, 4) Spatial autoregressive models, estimation and testing, 5) Spatial non-stationarity and associated modeling procedures and 6) Spatial sampling procedures. Use of open-source software (Primarily the R software package) with emphasis on analysis of real data from the environmental and social sciences will be the substantive focus of the class. Students will do a series of in-class labs and develop a final research project from these labs or an independent project.
Modern Data Structures (QMSS GR5072)
This course is intended to provide a detailed tour on how to access, clean, “munge” and organize data, both big and small. (It should also give students a flavor of what would be expected of them in a typical data science interview.) Each week will have simple, moderate and complex examples in class, with code to follow. Students will then practice additional exercises at home. The end point of each project would be to get the data organized and cleaned enough so that it is in a data-frame, ready for subsequent analysis and graphing. Therefore, no analysis or visualization (beyond just basic tables and plots to make sure everything was correctly organized) will be taught; and this will free up substantial time for the “nitty-gritty” of all of this data wrangling.
Machine Learning for Social Sciences (QMSS GR5073)
This course will provide a comprehensive overview of machine learning as it is applied in a number of domains. Comparisons and contrasts will be drawn between this machine learning approach and more traditional regression-based approaches used in the social sciences. Emphasis will also be placed on opportunities to synthesize these two approaches. The course will start with an introduction to Python, the scikit-learn package and GitHub. After that, there will be some discussion of data exploration, visualization in matplotlib, preprocessing, feature engineering, variable imputation, and feature selection. Supervised learning methods will be considered, including OLS models, linear models for classification, support vector machines, decision trees and random forests, and gradient boosting. Calibration, model evaluation and strategies for dealing with imbalanced datasets, n on-negative matrix factorization, and outlier detection will be considered next. This will be followed by unsupervised techniques: PCA, discriminant analysis, manifold learning, clustering, mixture models, cluster evaluation. Lastly, we will consider neural networks, convolutional neural networks for image classification and recurrent neural networks. This course will primarily us Python. Previous programming experience will be helpful but not requisite. Prerequisites: basic probability and statistics, basic linear algebra, and calculus.
Internship (QMSS GR5050 & QMSS GR5051)
Students enrolled in the Quantitative Methods in the Social Sciences MA program have a number of opportunities for internships with various organizations in New York City. All internships will be graded on a pass/fail basis.
An internship must meet the following criteria:
- It is related to the core issues of concern to the MA Program in Quantitative Methods in the Social Sciences.
- The work is substantive (although students may perform some administrative tasks, we want to ensure that they receive experience in substantive research).
- It is a practical, professional experience.
Practicum in Data Analysis (QMSS GR5052)
This practicum course is meant to offer valuable training to students. Specifically, this practicum will mimic the typical conditions that students would face in an internship in a large data-intense institution. The practicum will focus on four core elements involved in most internships: (1) Developing the intuition and skills to properly scope ambiguous project ideas; (2) practicing organizing and accessing a variety of large-scale data sources and formats; (3) conducting basic and advanced analysis of big data; and (4) communicating and “productizing” results and findings from the earlier steps, in things like dashboards, reports, interactive graphics, or apps. The practicum will also give students time to reflect on their work, and how it would best translate into corporate, non-profit, start-up and other contexts.
Independent Study (QMSS GR5998)
Students develop a course of study under the supervision of a faculty member. Please see the QMSS program coordinator for more details.

Mailman School of Public Health
BIST P6104 - Introduction to Biostatistical Methods
Course pre-requisites: Placement exam required, and the instructor's permission
Enrollment priorities: Priority given to BIO students
Like many fields of learning, biostatistics has its own vocabulary often seen in medical and public health literature. Phrases like "statistical significance", "p-value less than 0.05", "95% confident", and "margin of error" can have enormous impact in a world that relies on statistics to make decisions: Should Drug A be recommended over Drug B? Should a national policy on X be implemented? Does Vitamin C truly prevent colds? However, do we really know what these terms and phrases mean? Understanding the theory and methodology behind study design, estimation and hypothesis testing is crucial to ensuring that findings and practices in public health and biomedicine are supported by reliable evidence. This course covers the basic tools for the collection, analysis, and presentation of data. Central to these skills is assessing the impact of chance and variability on the interpretation of research findings and subsequent recommendations for public health practice and policy. Topics covered include: general principles of study design; estimation; hypothesis testing; several methods for comparison of discrete and continuous data including chi square test of independence, ttest, ANOVA, correlation, regression and logistic regression. This introductory course is a Core Course for the Biostatistics Department and is mandatory for all MS in Biostatistics students.
Columbia Business School
B8131-001: Sports Analytics
Sports analytics refers to the use of data and quantitative methods to measure performance and make decisions to gain advantage in the competitive sports arena. This course builds on the Business Analytics core course and is designed to help students to develop and apply analytical skills that are useful in business, using sports as the application area. These skills include critical thinking, mathematical modeling, statistical analysis, predictive analytics, game theory, optimization and simulation. These skills will be applied to sports in this course, but are equally useful in many areas of business.There will be three main topics in the course: (1) measuring and predicting player and team performance, (2) decision-making and strategy in sports, and (3) fantasy sports and sports betting. Typical questions addressed in sports analytics include: How to rank players or teams? How to predict future performance of players or teams? How much is a player on a team worth? How likely are extreme performances, i.e., streaks? Are there hot-hands in sports performances? Which decision is more likely to lead to a win (e.g., attempt a stolen base or not in baseball, punt or go for it on fourth down in football, dump and chase or not in hockey, pull the goalie or not in hockey)? How to form lineups in daily fantasy sports? How to manage money in sports betting? How to analyze various "prop'' bets?
