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.

DOI: 10.1080/03610926.2016.1242744

Abstract: ABSTRACT There are many estimators for population mean: arithmetic mean, median, root mean square, geometric mean, harmonic mean, and so forth. Which one is the best? Here, we answer this question given two measurements from… read more here.

DOI: 10.1080/03610926.2017.1417436

Abstract: ABSTRACT This paper proposes an efficient stratified randomized response model based on Chang et al.'s (2004) model. We have obtained the variance of the proposed estimator of πs, the proportion of the respondents in the… read more here.

DOI: 10.1534/genetics.119.302373

Abstract: The large state space of gene genealogies is a major hurdle for inference methods based on Kingman's coalescent. Here, we present a new Bayesian approach for inferring past population sizes, which relies on a lower-resolution… read more here.
