Welcome to the Companion Website

This site is intended to enhance your use of Practical Propensity Score Methods Using R, First Edition, by Walter Leite. Please note that all the materials on this site are especially geared toward maximizing your understanding of the material.

This practical book uses a step-by-step analysis of realistic examples to help students understand the theory and code for implementing propensity score analysis with the R statistical language. With a comparison of both well-established and cutting-edge propensity score methods, the text highlights where solid guidelines exist to support best practices and where there is scarcity of research. Readers will find that this scaffolded approach to R and the book’s free online resources help them apply the text’s concepts to the analysis of their own data. 


We gratefully acknowledge Walter Leite for writing an excellent text and creating the materials on this site.
