Discussion of "Impact of Frequentist and Bayesian Methods on Survey Sampling Practice: A Selective Appraisal" by J. N. K. Rao

TL;DR

This paper highlights the importance of model checking and fitting in survey sampling, advocating for unit level models especially in small area analyses to improve inference accuracy.

Contribution

It emphasizes the significance of model validation and advocates for the use of unit level models in small area survey inferences.

Findings

Model checking and fitting are crucial for accurate inferences.

Unit level models are valuable for small subpopulation analysis.

Enhances understanding of survey sampling methodologies.

Abstract

This comment emphasizes the importance of model checking and model fitting when making inferences about finite population quantities. It also suggests the value of using unit level models when making inferences for small subpopulations, that is, "small area" analyses [arXiv:1108.2356].
