Stochastic modelling of earthquake interoccurrence times in Northwest Himalaya and adjoining regions

Geomatics, Natural Hazards & Risk, 2018
This work concentrates on the distribution of earthquake interevent times in northwest Himalaya and its adjacent regions. We consider 12 time-dependent probability distributions for analysis.

A New Version of Kumaraswamy Distribution With Estimations and Applications

Engineering Reports, Volume 7, Issue 12, December 2025.
In this article, the unit interval in the Kumaraswamy distribution is extended to double‐bounded interval. The proposed model is constituted by the transformation of a logistic random variable with a power parameter, flexible enough to fit a wide range of real‐life scenarios involving risk evaluation.

Estimation of Parameters in Exponentiated-Weibull Distribution in Presence of Mask Data [PDF]

, 2015
When the lifetime data from the series system are masked, we consider the reliability estimation of exponentiated-Weibull distribution based on different masking level. We consider a series system of two independent component which follows exponentiated-

New Bivariate Exponentiated Modified Weibull Distribution [PDF]

Journal of Mathematics and Statistics, 2017
The new modified Weibull distribution named exponentiated modified Weibull distribution introduced by many authors. In this study, we define and study a bivariate modified Weibull distribution. Some joint probability functions and conditional probability density function are obtained. Also, joint survival function is expressed in compact form.

A Leptokurtic‐Form Birnbaum‐Saunders Distribution With Applications to Finance

Applied Stochastic Models in Business and Industry, Volume 41, Issue 6, November/December 2025.
ABSTRACT We propose here a new multivariate Birnbaum‐Saunders (BS‐type) distribution characterized by its leptokurtic property, making it particularly useful in the field of finance. Unlike the approach of Romeiro et al., our proposal is also based on scale mixtures of normal distributions (SMN), but with the mixing variable following a BS distribution,

Statistical Inference for the Alpha Logarithmic Power Transformed Exponential Distribution With Applications

Engineering Reports, Volume 7, Issue 11, November 2025.
The Alpha‐Logarithmic Power Transformed Exponential (ALPTE) distribution is introduced as a highly versatile lifetime model, demonstrating superior goodness‐of‐fit over common distributions (e.g., Gamma, Weibull) across diverse datasets. Its robust performance, even with data heterogeneity and outliers, showcases its adaptability for modeling various ...

On the Rayleigh Exponentiated Odd Generalized‐Inverse Exponential Distribution With Properties and Applications

Engineering Reports, Volume 7, Issue 11, November 2025.
This research centers on the creation of an innovative statistical model that extends the inverse exponential (IE) distribution by employing the Rayleigh‐exponentiated odd generalized (REOG) family of distributions, which is designated as the REOG‐IE distribution.

Topp–Leone Modified Weibull Model: Theory and Applications to Medical and Engineering Data

Applied Sciences, 2022
In this article, a four parameter lifetime model called the Topp–Leone modified Weibull distribution is proposed. The suggested distribution can be considered as an alternative to Kumaraswamy Weibull, generalized modified Weibull, extend odd Weibull ...

A New Weibull-G Family of Distributions [PDF]

, 2016
Statistical analysis of lifetime data is an important topic in reliability engineering, biomedical and social sciences and others. We introduce a new generator based on the Weibull random variable called the new Weibull-G family.
