    PENAKSIR RASIO-PRODUK EKSPONENSIAL YANG EFISIEN UNTUK RATA-RATA POPULASI PADA SAMPLING ACAK BERSTRATA
    (2014-03-25) Nuryalita, Dessy; Efendi, Rustam; Sirait, Haposan
    This paper discusses three estimators for the population mean in the stratified random sampling, the exponential ratio estimator and exponential product estimator proposed by Singh [4] and combination exponential ratio-product estimator proposed by Singh and Vishwakarma [3]. The three estimators are biased estimators. The most efficient estimator is an estimator that has the smallest mean square error obtained by comparing the mean square error of each estimator.
