Unreadable Document Analysis by Mrigendra Mishra is a document available to read on EtoBox.
This document proposes a combined ratio-product estimator to estimate the mean of a finite population in stratified sampling when auxiliary information is available. It derives the bias and variance of the proposed estimator under large sample approximations. An asymptotically optimum estimator in the class is identified, along with its variance formula. An estimator based on the estimated optimum value is also investigated, and it is shown that its variance is the same as the optimum estimator. Both theore
