Item KOMBINASI PENAKSIR RASIO DAN PENAKSIR REGRESI UNTUK RATA-RATA POPULASI MENGGUNAKAN MEDIAN DAN KOEFISIEN SKEWNESS PADA SAMPLING ACAK SEDERHANA(2014-03-25) Sakinah; Efendi, Rustam; Gamal, M. D. HIn this artikel the combination of ratio estimators and ratio regression in simple random sampling using median and coefficient of skewness are discussed, which is a review and an expansion from the article J. Subramani & G. Kumarapandiyan [American Journal of Matematics and Statistics, 2(5): 101-107]. The estimators are biased estimators and the mean square errors are determined. Estimator with the smallest mean square error is the most efficient estimator. A numerical example is given at the end of discusssion.
