Household surveys used by countries to quantify the main social indicators have a complex design, stratified, multi-stage, and with unequal inclusion probabilities. The estimates from these statistical operations are subject to sampling error, and it becomes necessary to evaluate their statistical validity through various precision and reliability indicators.

This activity focuses on presenting the R library “Calidad”, a set of methodological tools to assess the quality of an estimate towards objective criteria of the estimate’s reliability in complex household surveys. Some applications are illustrated with actual survey data sets.

This library was developed in Latin America by the Chilean National Statistical Institute and is available in the official Comprehensive R Archive Network (https://cran.r-project.org/package=calidad).
