Some Improved Estimators In Systematic Sampling Under Non-response

Autor: Verma, Hemant K., Singh, R. D., Singh, Rajesh

Publikováno v: nat. acad. sci. let., 37(1)-91-95, (2014)

In this paper we have considered the problem of estimating the population mean in systematic sampling using information on an auxiliary variable in presence of non response. Some modified ratio, product and difference type estimators in systematic sa

A general class of regression type estimators in systematic sampling under non-response

Autor: Verma, Hemant, Singh, R. D., Singh, Rajesh

Publikováno v: Octogon Mat. Mag. 20(2), 542-550 (2012)

In this paper we have proposed a general class of modified regression type estimator in systematic sampling under non-response to estimate the population mean using auxiliary information. The expressions of bias and mean square error (MSE) up to the

Exponential Ratio Type Estimators In Stratified Random Sampling

Autor: Singh, Rajesh, Kumar, Mukesh, Singh, R. D., Chaudhry, M. K.

Kadilar and Cingi (2003) have introduced a family of estimators using auxiliary information in stratified random sampling. In this paper, we propose the ratio estimator for the estimation of population mean in the stratified random sampling by using
