Inference on Exponentiated Power Lindley Distribution Based on Order Statistics with Application

Abstract

Exponentiated power Lindley distribution is proposed as a generalization of some widely well-known distributions such as Lindley, power Lindley, and generalized Lindley distributions. In this paper, the exact explicit expressions for moments of order statistics from the exponentiated power Lindley distribution are derived. By using these relations, the best linear unbiased estimates of the location and scale parameters, based on type-II right-censored sample, are obtained. Next, the mean, variance, and coefficients of skewness and kurtosis of some certain linear functions of order statistics are calculated and then used to derive the approximate confidence interval for the location and scale parameters using the Edgeworth approximation. Finally, some numerical illustrations and two real data applications are presented.

A Three Parameter Power Nakagami Distribution: Properties and Application on the Tax Revenue Data

“…Applicability and flexibility of the proposed distribution are shown by utilizing the flood dataset. Inferences on exponentiated power Lindley distribution with order statistics was proposed by [11]. The cubic spline interpolation was used by [8] to obtain the closed form of the inverse cumulative distribution function of the Nakagamim distribution.…”

An Extended log-Lindley-G Family: Properties and Experiments in Repairable Data

“…Al-Babtain et al [5] proposed a new version for a discrete analog of the continuous Lindley law. Beyond extensions of the Lindley distribution, improved statistical inference tools have been derived from it [6][7][8][9].…”
