Improvement in Estimating the Population Mean Using Exponential Estimator in Simple Random Sampling

Rajesh Singh, Pankaj Chauhan, Nirmala Sawan, Florentin Smarandache

Abstract


This study proposes some exponential ratio-type estimators for estimating the population mean of the variable under study, using known values of certain population parameter(s). Under simple random sampling without replacement (SRSWOR) scheme, mean square error (MSE) equations of all proposed estimators are obtained and compared with each other. The theoretical results are supported by a numerical illustration.

Keywords
