Variance estimation with post stratification. Suppose we post stratify the sample into L post strata, with population

Question:

Variance estimation with post stratification. Suppose we post stratify the sample into L post strata, with population counts N1, N2. . . NL. Then the post stratified estimator for the population total is

Where

And xli =1 if unit i is in post stratum l and 0 otherwise. Show, using linearization, that

We can thus let

and estimate V(ṫpost) by
