Test LOT Quality Assurance Sampling Method in Estimating Communes with Improved Latrine in Vietnam

Nguyen, Cuong (2017): Test LOT Quality Assurance Sampling Method in Estimating Communes with Improved Latrine in Vietnam.

Abstract

In this study, we will simulate different ways of select households according to the LC-LQAS method, and examine the accuracy of these ways to measure the percentage of communes having the sanitation coverage of 70%. We tried different sampling methods which differ in the number of clusters (village) and the number of households selected in each communes. The results suggest that the methods identify communes with the sanitation rate of at least 70% quite well. More than 90% of communes are correctly identified. The number of clusters selected in a commune plays an important role in reducing the mean squared error and increasing the correct prediction rates. Possible, two clusters within a commune with the total number of sampled households of 19 is the best choice.
