Estimation of Population Median in Successive Sampling

H.S. Jhajj, Harpreet Kaur, Puneet Jhajj


In trivariate population, using prior information on population median of one of the auxiliary variable, a generalized estimator of population median of the study variable has been proposed under successive simple random sampling design. The expressions of biases, mean squared errors and their optimum values have been obtained for the case of finite and infinite population. It has also been shown theoretically that proposed estimator is always better than the linear regression type estimator. Numerical illustration of results obtained have also been done by taking populations considered in literature which also show that the proposed estimator is almost two times efficient than the linear regression type estimator.

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.
