Alpha Power Moment Exponential Model with Applications to Biomedical Science

Abstract

The moment exponential distribution has recently been generalized by a number of authors. The two-parameter alpha power-transformed moment exponential (APTME) distribution is introduced. In terms of fit, the APTME distribution outperforms the moment exponential distribution. Exact expressions for ordinary moments, incomplete and conditional moments, the moment generating function, the cumulant generating function, and information measures are obtained for some APTME distribution features. To estimate the model parameters, six well-known frequentist techniques were applied. The behavior of the various estimators was investigated using a simulated exercise. To examine the practical significance of the APTME distribution, real-world datasets were used. In terms of performance, we show that the APTME distribution beats other models.

A New Class of Generalized Extreme Value Distribution and Application under Alpha Power Transformation Method

“…In 2019, Ihtisham et al [8] studied a new distribution referred to as the Alpha-Power Pareto distribution, which is an extra parameter, and two real datasets have been considered to examine the usefulness of the proposed distribution. In 2022, Shrahili et al [17] introduced two-parameter alpha power transformed moment exponential (APTME) distribution. To examine the practical significance of the APTME distribution and real-world datasets.…”

Information Approach for Change Point Analysis of EGGAPE Distribution and Application to COVID-19 Data

“…Hassan et al [6] obtained weighted power Lomax distribution and its length biased version. Shrahili et al [7] discussed the alpha power moment exponential model with applications to biomedical science. Chen and Arjun [8] did an extensive study on the statistical change point in the parametric context and gave applications related to the elds of nance, medicine, and genetics.…”
