A Gentle Introduction to Causal Modelling with Stata (Dubai)

Sofitel, Downtown Dubai 3 days (27th March 2019 - 29th March 2019) Stata Intermediate

Overview

Modelling causal relationships is of the utmost importance in both the social and biomedical sciences. Assessing existence, sign, and direction of mutual relationships among the variables of a dataset can in fact serve many purposes: effect evaluation of policy interventions, detection of the mediating role played by some exposure to medical treatments, analysis of direct and indirect effects generated by external changes in many different contexts.

Typically, causal models are based on systems of equations, which are analysed using regression analysis techniques. The estimated relations are often mapped in diagrams or flow graphs.

The objective of this course is to provide participants with a gentle introduction to the essential toolset, mainly applied, for the implementation of simple structural equation models (SEM) for causal modelling in Stata, using the Stata package sem. This course offers two perspectives upon the issue, one focused on models where cross-section datasets are available; the other focused on times-series data. The former allows for causal path analysis. The latter also permits scenario-building and policy evaluation over time.

At the end of the course, participants will be able to autonomously undertake simple but effective causal designs studies to identify, estimate and test for both direct and indirect effects, pathways, and scenario building.

The course will be highly practical and focused on Stata applications using the sem package.

In common with Timberlake courses’ philosophy, participants will obtain extensive hands-on experience of the issues under consideration, working on example datasets from both the social and biomedical sciences under the careful guidance of the course instructor.

Too burdensome technical treatment will be avoid. Participants will be practise real world applications.
