Question:

In Example 6.11, we calculated the with-replacement variance for á¹«HT. In this example, the sampling fraction n/N is 1/3, so the with-replacement variance is likely to overestimate the without-replacement variance. The joint inclusion probabilities for the psus are given in file classppsjp.dat, and can also be obtained by running the SAS program given on the website.
a. Calculate á¹¼HT (á¹«HT) and Ë†VSYG (á¹«HT) for this data set.
b. SAS software approximates the without-replacement variance in unequal-probability sampling using
