Truncated Modified Weibull: Estimation and Predication Based on Maximum Likelihood Method [PDF]

open access: yesالمجلة العملیة التجارة والتمویل, 2018
In this paper, a truncated modified Weibull distribution is introduced as a lifetime distribution, where all the parameters and the truncated points are unknown. Theprobability density function, cumulative distribution function, reliability, hazard rate and reversed hazard rate functions are obtained with graphical description.

Bias Reduction of Maximum Likelihood Estimates for an Asymmetric Class of Power Models with Applications

open access: yesRevstat Statistical Journal, 2023
In this paper we study some methods to reduce the bias for maximum likelihood estimation in the general class of alpha power models, specifically for the shape parameter. We find the modified maximum likelihood estimator using Firth's method and we show

Odds Ratio Estimation for Small Count in Zero-Inflated Poisson

open access: yesIEEE Access, 2020
The odds ratio estimation when observed frequencies are very small usually causes difficulty in calculation. In this paper, we proposed the estimator of odds ratio for small count using Empirical Bayes (EB) in Zero-inflated Poisson distribution, where ...
