DOI: 10.1080/03610926.2017.1300280
Abstract: ABSTRACT In this article, we propose a new difference-type estimator in estimating the finite population mean in stratified double sampling by using the ranks of two auxiliary variables as an additional information. The proposed estimator… read more here.

DOI: 10.1080/03610926.2017.1342836
Abstract: ABSTRACT This study proposes a more efficient calibration estimator for estimating population mean in stratified double sampling using new calibration weights. The variance of the proposed calibration estimator has been derived under large sample approximation.… read more here.

DOI: 10.1080/08982112.2020.1738481
Abstract: Abstract Control charts based on inspection with gauges are an interesting alternative to monitor quantitative variables when measurement is complex or expensive. The main advantage over variable control charts lies in greater operational simplicity and… read more here.
