Two Stage Cluster Sampling Formula. I j 1 m i y i j m i The first part of this formula is also known as the expansion estimator. Calculate the overall basic weight of an individual being sampled in the population.
As 1 and in the situations with small cluster size this approximation may not be justified. BW1prob 1 prob 2. When sampling clusters by region called area sampling.
I am using three-stage cluster sampling with unequal sizes.
