Abstract

A new member from the T-X family of distribution called the Gumbel-Dagum (GUD) distribution is introduced. This was realized by adopting the logit transformation of the cumulative distribution function of the Dagum random variable and the Gumbel distribution as the generator. Some mathematical properties of the new distribution are presented including the maximum likelihood .estimator of its parameters.
