(2009), Singh and Solanki (2013 a, b), Singh et al. (2014), Solanki and Singh (2016), Mehta and Mandowara (2016), Saini and Kumar (2016), Mehta et al. (2020) and Bhushan and Kumar (2022) which cover most of the familiar estimators. The optimality conditions have been established and followed up by a simulation study as well as a real data application and the results are constituted a rather satisfactory showing advancement over the all prominent estimators discussed in this article.
