摘要：
An estimator rg of the population correlation coefficient has been suggested in case of probability proportional to size with replacement sampling. The asymptotic bias, variance and the estimate of the variance of the estimator rg have been obtained. A comparison of this estimator has been made with the estimator r given by Gupta et al (1993) and usual estimator r1 for PPSWR sampling. The proposed estimator rg satisfies the condition -1≤ rg ≤ 1 which the estimator r does not satisfy.
