Recent studies have highlighted the statistical relevance and applicability of trigonometric
distributions for the modeling of various phenomena. This paper contributes to the subject by …

The goal of this paper is to develop an optimal statistical model to analyze COVID‐19 data in
order to model and analyze the COVID‐19 mortality rates in Somalia. Combining the log …

In this article, we introduce a new extended cosine family of distributions. Some important
mathematical and statistical properties are studied, including asymptotic results, a quantile …

An extension of the cosine generalized family is presented in this paper by using the cosine
trigonometric function and method of parameter induction concurrently. Prominent …

In this article, we extensively study a family of distributions using the trigonometric function.
We add an extra parameter to the sine transformation family and name it the alpha-sine-G …

This article proposes a new lifetime-generated family of distributions called the sine-
exponentiated Weibull-H (SEW-H) family, which is derived from two well-established …

This study introduces the family of the novel” cot-generator” distributions based on the
cotangent function. The construction of the probability density function based on the cot …

Although there are many continuous distributions in the literature, only a handful take
advantage of the modeling power provided by trigonometric functions. To our knowledge …

This study introduces a novel family of probability distributions called the” tangent
exponential-G family,” which is derived using trigonometric transformations of the …

In recent years, the trigonometric families of continuous distributions have found a place of
choice in the theory and practice of statistics, with the Sin-G family as leader. In this paper …
