Abstract |
|
The problem of estimation of finite population median at current occasion in two occasion successive sampling has been
considered using the additional auxiliary variate which is dynamic over time and is readily available at both the occasions. Properties
of the proposed estimators including the optimum replacement strategies have been elaborated. The density functions appearing in
the results have been estimated by the method of generalized nearest neighbour density estimator related to kernel estimator. The
dominance of the proposed estimators is shown over sample median estimator when there is no matching from previous occasion as
well as over the ratio type estimator proposed by Singh et al. [H.P. Singh, R. Tailor, S. Singh and J.M. Kim, Journal of the Korean
Statistical Society, 36(4), 543-556 (2007)] for second quantile. The behaviours of the proposed estimators are justified by empirical
interpretations and validated by means of simulation study with the help of a natural population. |
