Under a linear regression model, the best linear unbiased estimator (BLUE) for a finite population total can be obtained. The problem studied here is that of estimating the variance for setting ...

Double sampling of a finite population occurs when a sample from the population is itself sampled, with the intent of measuring variates in the subsample not already available in the sample. An ...
