Estimation of the Population Mean in Presence of Non-Response
Estimation of the Population Mean in Presence of Non-Response
In this paper following Singh et al. (2008), we propose a modified ratio-product type exponential estimator to estimate the finite population mean <TEX>$\={Y}$</TEX> of the study variable y in presence of non-response in different situations viz. (i) population mean <TEX>$\={X}$</TEX> is known, and (ii) population mean <TEX>$\={X}$</TEX> is unknown. The …
