# POL50050 Quantitative Methods II

This course seeks to extend the analytical and theoretical understanding developed in Quantitative Methods I. It covers the fundamentals of regression analysis, starting with extensions to the basic linear model and then introducing the generalized linear model as applied to limited (categorical and count) dependent variables. While the course mostly considers modelling as a general tool for prediction, several sessions in the second part focus on methods for inferring causal effects from observational data.

This course is applied. A certain degree of mathematical and theoretical discussion is indispensable to gain a sufficiently deep insight into the methods covered. However, the emphasis is on understanding, implementation, and interpretation of the various techniques in the context of actual research. This approach is reflected in the choice of texts and in the focus on practical coursework. Consequently, the learning method combines lectures and reading with statistical programming exercises using real datasets.

The statistical package being used is R.

Learning Outcomes:

At the end of this course, students will be able to:
--- Outline core assumptions of the linear regression model;
--- Diagnose problems when applying the linear model to real data and choose appropriate corrections;
--- Apply generalizations of the linear model to limited dependent variables (categorical and count data) and interpret the results;
--- Explain and (where possible) test assumptions of causal inference techniques and use these with real data;
--- Select, run, and interpret a fairly complex regression model to answer a practical research question.

Approaches to Teaching and Learning:
The class time will be a mixture of lectures and guided hands-on work with actual data. Students need to work on regular homeworks conducting similar applied analyses.
