  • Resources on How to Obtain and Use Nonpublic Administrative Data

    J-PAL North America developed this pair of resources to support the use of nonpublic administrative data for randomized evaluations. The guide provides general tips on how to obtain and use these data. The catalog of key US data sets provides agency-specific information on how to request data.

  • J-PAL Costing Guidelines

    This document provides an outline on how to approach collecting cost information, what costs to include and exclude, and how detailed cost data should be.

  • Guide: Writing Randomization Code in Stata

    This step-by-step guide uses data and an annotated Stata do-file to illustrate how a simple randomization can be carried out using Stata.

  • IPA's Best Practices for Data and Code Management.

    IPA's data publication guideline covers the principles of organizing and documenting data and code – illustrated using examples from Stata – at all steps of the project lifecycle with the goal of making research reproducible.

  • Household Poverty Measurement

    The PPI is a leading household poverty measurement tool, used by more than 500 organizations around the world, to measure household poverty, improve targeting and social performance, and track changes in welfare. It is a country-specific ten-question scorecard that estimates whether a particular household is living below the poverty line.

Stata 102

In this Stata module, you have some Stata experience (say in a college class) but would not consider yourself particularly comfortable with the program. You are very familiar with the following concepts:

  • Descriptive commands such as summarize, tabulate, and list
  • Conditions: if, and (&), and or (|) 
  • Data manipulation commands such as generate, replace, and drop

You are likely somewhat familiar with:

  • Creating and writing do-files
  • Sorting and saving datasets
