Sampling on two occasions: Estimation of population total

Two sampling strategies have been proposed for estimating the finite population total for the most recent occasion, based on the samples selected over two occasions involving varying probability sampling schemes. Attempts have been made to utilize the data collected on a study variable, in the first occasion, as a measure of size and a stratification variable for selection of the matched-sample on the second occasion. Relative efficiencies of the proposed strategies have been compared with suitable alternatives.
