An efficient Hartley–Ross type estimators of nonsensitive and sensitive variables using robust regression methods in sample surveys
Zaman, Tolga; Shazad, Usman; Yadav, Vinay Kumar (Elsevier B.V., 2023)In sample surveys, the problem of outliers is one of the most frequent and widest, whose solution is required to be obtained using statistical techniques. To overcome this problem, various robust regression methods are ... -
A general class of improved population variance estimators under non-sampling errors using calibrated weights in stratified sampling
M K Pandey; G N Singh; Tolga Zaman; Aned Al Mutairi; Manahil SidAhmed Mustafa (National Library Of Medicine, 2024)This paper proposes a new calibration estimator for population variance within a stratified two-phase sampling design. It takes into account random non-response and measurement errors, specifically applying this method to ... -
