WebHoyle noted an interesting, just-published application. 3 It uses the finite population correction factor in a multilevel model when the level two variable represents a small cluster population. Interestingly the authors argue that the usual choice by people using multilevel modeling is a fixed effect model versus a random effects model. WebPopulation size -- Leading to a discussion of "infinite" populations. When we sample without replacement, and get a non-zero covariance, the covariance depends on the population size. If the population is very large, this covariance is very close to zero. ... versus sampling from a finite population (without replacement). Mary Parker ...
