A Transmuted Modified Power-Generated Family of Distributions with Practice on Submodels in Insurance and Reliability

Abstract

In this article, we propose a new transmuted modified power-generalized family of distributions constructed from the transmuted-generated and modified power-generated families. The proposed approach is flexible and provides a tradeoff between the two baseline families. For a prime study, we identify the main characteristics of the new transmuted modified power family, such as the asymptotic results, quantile function, series representation, and the various kinds of moment measures. By using the exponential distribution as the baseline, a new three-parameter lifetime distribution is constructed. The associated probability functions (density and hazard rate) are flexible and have a variety of asymmetric shapes, which make them attractive for statistical purposes. In particular, for the related probability density function, reversed-J, unimodal, and right-skewed shapes are observed. Measures relating to risk theory are also computed, such as the value at risk and the expected shortfall. By using both simulation analysis and the maximum likelihood approach, the estimation of the model parameters is evaluated. The effectiveness of the proposed model is demonstrated by two real-world cases (one in insurance and the other in reliability), and we show that it yields better fits when compared to other extended models connected to the exponential model.

“…This involves modifying a baseline distribution by substituting it into the families of distributions. Some families of distributions developed include Kumaraswamy-G (Kw-G) [1], Zubair-G family [2], Sin-G [3,4], Cos-G [3,4], Tan-G [3], extended odd Fréchet-G family [5], arcsine exponentiated-X family [6], tangent Topp-Leone-G [7], Marshall-Olkin Zubair-G [8], secant-G class (Sec-G) [9], new cotangent-G [10], cosine Topp-Leone-G [11], weighted cosine-G [12], transmuted modified power-generated family [13], modified-half normal family [14], and logistic cotangent exponentiated generalized family [15].…”
