recommendations! Published in 2020 at "Journal of statistical theory and practice"

DOI: 10.1007/s42519-020-00140-5

Abstract: This paper is an effort to investigate the effect of non-response at the current (second) occasion in successive sampling. Using the subsampling non-respondent procedure, some exponential-type estimators have been proposed to estimate the current population… read more here.

recommendations! Published in 2019 at "Journal of King Saud University - Science"

DOI: 10.1016/j.jksus.2018.12.005

Abstract: Abstract In this article, we propose a general family of exponential-type estimators for enhanced estimation of population mean in simple random sampling. These estimators are based on the available parameters of the auxiliary variable such… read more here.

recommendations! Published in 2019 at "Journal of Statistical Computation and Simulation"

DOI: 10.1080/00949655.2019.1586905

Abstract: ABSTRACT In the present article, we propose the generalized ratio-type and generalized ratio-exponential-type estimators for population mean in adaptive cluster sampling (ACS) under modified Horvitz-Thompson estimator. The proposed estimators utilize the auxiliary information in combination… read more here.
