Improved estimators of variance of the regression estimator in two-phase sampling

Oregon Convention Center 

In this paper, a few interesting estimators for estimating the variance of the regression estimator in two phase sampling have been considered. An improved Jackknife technique for estimating the variance of the regression estimator in two-phase sampling has been suggested. The jackknife estimator proposed by Sitter (1997: Journal of the American Statistical Association, pp. 780-787) has been shown to be a special case of the proposed strategy. Improved strategies are based on the estimation techniques suggested by Isaki (1983: Journal of the American Statistical Association, pp. 117-123) for estimating the finite population variance. An empirical study has been carried out to show the performance of the proposed strategies over the Sitter estimators.
