Preamble

This online book consists of the solutions for the (fictional) HISP program evaluation example used throughout the great (free!) book Impact Evaluation in Practice (2nd Edition) by Gertler, Martinez, Premand, Rawlings, and Vermeersch released by the World Bank Group and the Inter-American Development Bank. https://openknowledge.worldbank.org/handle/10986/25030

These solutions are part translation/extension of the original Stata code, part relevant extracts from the book, and some additions I made when teaching this material. As you’ll see, the code generally follows the tidyverse approach to R, with some exceptions here and there.

Usual caveats apply.
