Advanced Course in Multiple Regression and Causal Inference

About This Course

Every researcher wants to be sure that observed associations are valid. After using bi-variate tests (such as chi-squared test, t-test, ANOVA, etc) to demonstrate association between two variables of interest, the next critical question is whether those associations are valid i.e. whether they can in fact be explained by other variables (confounding) or study methodology (bias). In other words, in strengthening causal inference, it is vital to eliminate the role of confounding and bias. Multiple regression remains the most well-known approach for controlling for confounding and estimating independent effects.

Multiple regression models are used to determine risk factors after adjusting for confounding. They are also commonly used to build models for predicting an outcome. Therefore, researchers should be able to build, understand and interpret multiple regression models.

The course is taught using Stata. So, it is a pre-requisite that the participants have at least one of the following:

  • Have attended CESAR’s level 1 course: Data Analysis and Management Course using Stata
  • Have previous experience working with Stata
  • Have no previous experience with Stata but can conduct bi-variate tests using another statistical package.

Course outcomes

The course will teach participants the following:

This course teaches participants to fit multiple regression models and estimate measures of effect. Simple and multiple regression models for crude and adjusted effects will be covered. Three types of regression models will be covered – linear, quantile and logistic regression. The course uses a fine blend of didactic lectures, group exercises for every session and two project reports that simulate real life scenarios. 

After the course, participants will be able to understand the link between bi-variate tests and regression model, for example, the link between t-test and linear regression and chi-squared test and logistic regression. They will also be able to build causal or predictive models and interpret the outputs. Furthermore, they will be able to adjust for confounders and estimate independent effects, thereby strengthening causal inference in their research.
