Session 1: How to calculate the validity and reliability of poverty measures

Dr Héctor Nájera (UNAM, Mexico)

This is a practical session that will introduce the computation of the different reliability estimators -alpha, beta and omega- using the R-software. After a brief introduction to R, the participants will see a live computation of reliability using different datasets. In additions participants will have access to a handbook to perform and reproduce the computations.

The second part of the session focuses on the methods to estimate criterion and construct validity using structural equation modelling. Most of the calculations will be based on the lavaan R-package.‌
