ON A NEW SKEW GENERALIZED LOGISTIC DISTRIBUTION

Print ISSN: 2319-1023

Abstract

In this paper, we propose a new skew generalized logistic distribution, which is an extension of the logistic distribution, the generalized logistic distribution, proposed by Rathie and Swamee [11] and the Kumaraswamy Logistic distribution, proposed by Santana et al. [13]. We study various mathematical properties of the new distribution, including explicit formulas for the probability density function, cumulative distribution function, survival, hazard and quantile functions. We also derive formulas for the moments, mean and median deviations, the Lorenz and Bonferroni curves. We also study some statistical properties, such as distributions of the minimum and the maximum order statistics. This distribution is used in two applications with real data: the rst data is bimodal, and the second unimodal.

Keywords and Phrases
