Conjugate and objective priors for the parameter and cumulative function under bathtub and increased shapes of hazard function

Fernando A. Moala, Aroldo J. Costa, Luis F. Jorge, Sérgio M. Oikawa

Published Online: 01 Mar 2025DOI: 10.47974/JSMS-969

In this paper: We present a full Bayesian inference for the parameter and the associated reliability function of the Exponentiated Gamma distribution. This distribution has the advantage of being uni-parametric and...

Cure rate and statistical inference for the Marshall-Olkin generalized defective Gompertz distribution under censored survival data

Tasnime Hamdeni, Soufiane Gasmi

Published Online: 01 Mar 2025DOI: 10.47974/JSMS-978

In this paper: Cure fraction modeling usually requires the addition of an extra parameter. Defective modeling, alternatively, allows cure fraction modeling with less complexity. A new extension of the defective vers...

The classical, meta-heuristic and EM algorithms for the estimation of the KM-Weibull distribution under progressively first-failure censoring

Sümeyra Sert, Ihab Abusaif, Ahmet Pekgör, Kadir Karakaya, Coşkun Kuş

Published Online: 01 Mar 2025DOI: 10.47974/JSMS-1199

In this paper: In life testing, collecting data is difficult for high-technology products since they are too expensive and have long lifetimes. From this perspective, some censoring schemes are introduced, and the m...

Mixture unit Weibull distribution : Properties and applications

Festus W. Kparibire, Suleman Nasiru, Abdul-Aziz Adam Kobilla, Abdul Ghaniyyu Abubakari

Published Online: 01 Mar 2025DOI: 10.47974/JSMS-1270

In this paper: In this study, two component mixture unit-Weibull (TCMUW) model is proposed for fitting data on (0, 1) interval by mixing two unit-Weibull models. The density function plots give the impression that t...
