The present paper deals with a modified ratio estimator for estimation of population mean of the study variable when the population median of the auxiliary variable is known. The bias and mean squared error of the proposed estimator are derived and are co... see more

This paper deals with the problem of estimating the finite population mean using auxiliary information in simple random sampling. Firstly we have suggested a correction to the mean squared error of the estimator proposed by Gupta and Shabbir [On improveme... see more

This paper deals with the problem of estimation of population mean in two-phase sampling. A ratio-product estimator of population mean using known coefficient of kurtosis of two auxiliary variates has been proposed. In fact, it is a two-phase sampling ver... see more

Chicken eggs are a type of egg that is easy to find and favored by many people. So that the community's need for chicken eggs is needed to meet the needs of animal protein sources and their daily nutrition. This study analyzes the application of the K-Mea... see more

The aim of this paper was to analyze, within a group of 21 females from Romanian Mioritic Shepherd Dog breed, 13 characters of genetically improved, characters stipulated in „Selection sheet and body measurements for Romanian shepherds". The animals were ... see more

This paper presents a new general family of estimators to estimate the population mean of study variable y in the presence of non-response when utilizing a known coefficient of variation of study variable y. The expressions for bias, mean squared error (M... see more

This paper proposes two new classes of ratio estimators for population mean when information on a known auxiliary variable is available in simple random sampling. A combined family of ratio estimators for estimating population mean by combining the two ne... see more
