Hello and welcome!

This website gathers all the materials for the paper Matching Methods for Environmental Epidemiology: A Tutorial by Tarik Benmarhnia, Marie-Abèle Bind, and Léo Zabrocki.

To illustrate how matching procedures work, we study the effect of heat waves on daily number of years of life lost (YLL) in Montreal over the 1990-2007 period.

The website is structured as follows:

• A PDF version of the working paper is accessible through the Paper.
• The Data tab describes the sources of the data and the definition of the variables. It also contains a detailed exploratory data analysis of the covariates balance.
• The Standard Approach tab presents results found with an outcome regression model.
• The Matching tab contains the analysis of three matching procedures: propensity score matching, coarsened exact matching and cardinality matching.
• The Summary tabs gathers all results found with the different procedures.
• All the R code for this tutorial is available in its GitHub directory and in an Open Science Framework repository.
