- Articles and reports: 12-001-X20030016612Description:
In the present investigation, we introduce new calibration equations to estimate the population mean in stratified simple random sampling, making use of second order moments of the auxiliary character. We also suggest ways for estimating the variance of the proposed estimator. The resultant new estimator can be more efficient in stratified sampling than the combined regression estimator. Thus, we have extended the idea to double sampling in a stratified population and have studied the simulation results.
Release date: 2003-07-31 - Articles and reports: 12-001-X19980024355Description:
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.
