Penaksir Rasio Untuk Rata-Rata Populasi Menggunakan Standar Deviasi, Koefisien Skewness Dan Koefisien Kurtosis Pada Sampling Ganda
ABSTRACT
This final project discusses three type ratio estimators for population’s
mean using standard deviation, coefficient of skewness and coefficient of kurtosis on double sampling which is a review from the article of Singh et al. [Italian Journal of Pure and Applied Mathematics-N. 28 (2011), 135-142]. The three estimators are biased estimators. Then the mean square error (MSE) of the three estimators are determined. Furthemore the mean square error of each estimators are compared. The smallest mean square error of the estimators is the most efficient estimator.
Keywords: Ratio estimator, bias, mean square error, double sampling, standard deviation, coefficient of skewness, coefficient of kurtosis
