An Estimator of the Correlation Coefficient in Probability Proportional to Size without Replacement Sampling

摘要

The present paper deals with the problem of estimating the correlation coefficient for finite population in case of Probability Proportional to Size without Replacement Sampling. Asymptotic expressions for the bias, an upper limit of the bias, variance and an estimate of variance of the proposed estimator for finite population correlation p have been obtained. An empirical investigation has also been made.
