Understanding the context for agriculture for nutrition research: Identifying country typologies of child-stunting determinants:

Maruyama, Eduardo; Unnevehr, Laurian J.; Wang, Jiarui - International Food Policy Research Institute (IFPRI) - 2014

We use data from 52 countries on child stunting, poverty, determinants of food security, environmental health, and quality of maternal and child care to carry out a cluster analysis of country typologies. The purpose is to identify where agriculture-led interventions might address binding...

Understanding and Teaching Within-Cluster Correlation in Complex Surveys

Barreto, Humberto; Raghav, Manu - Department of Economics and Management, DePauw University - 2013

This econometrics pedagogy paper demonstrates the importance of using cluster standard errors with data generated from complex surveys. Simulation is used to show that both classic ordinary least squares and robust standard errors perform poorly in the presence of within-cluster correlated...
