Product-Product-Type (PPT) Exponential Estimator in Double Sampling for Stratification (DSS) of Finite Population Mean

Housila P. Singh, Pragati Nigam

Abstract



In this research work we have suggested an exponential estimator of product-product-type (PPT) in double sampling for stratification (DSS). We’ve obtained the bias and mean squared error (MSE) to the first degree of approximation (fda) of the developed estimator. Comparisons have been made theoretically and numerically both with unbiased estimator, estimator of product-type and exponential estimator of product-type. The work is also supported by an empirical analysis.

Keywords


Bias, MSE, Auxiliary variable (A.V.), DSS.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
