Abstract

Statisticians have created and proposed new families of distribution by extending or generalizing existing distributions. These families of distributions are made more flexible in fitting different types of data by adding one or more parameters to the baseline distributions. In this article, we present a new family of distributions called Type II half-logistic exponentiated-G family of distributions. We discuss some of the statistical properties of the proposed family such as explicit expressions for the quantile function, probability weighted moments, moments, generating function, survival and order statistics.  The new family’s sub-models were discussed.  We discuss the estimation of the model parameters by maximum likelihood.  Two real data sets were employed to show the usefulness and flexibility of the new family
