On Generalized q-logistic Distribution and its Characterizations
Abstract
Several generalizations of the logistic distribution, and certain related models, are proposed by many authors for modeling various random phenomena such as those encountered in data engineering, pattern recognition, and reliability assessment studies. A generalized q-logistic distribution is discussed here in the light of pathway model, in which the new parameter q allows increased flexibility for modeling purpose. Also, we discuss different properties of the two generalizations of the q-logistic distributions, which can be used to model the data exhibiting a unimodal density having some skewness present. The first generalization is carried out using the basic idea of Azzalini and we call it as the skew q-logistic distribution. It is observed that the density function of the skew q-logistic distribution is always unimodal and log-concave in nature.
