Estudo sobre algumas famílias de distribuições de probabilidades generalizadas.

Abstract

The purpose of this dissertation is to study the main families of generalized probability distributions. Particularly we study the distributions Beta Pareto, generalized Beta Exponential, Beta Modified Weibull, Beta Fréchet and Kw-G. For each one of these distributions we obtain expressions for the probability density function, cumulative distribution function, hazard function and moment generating function as well as parameter estimates by the method of maximum likelihood. Finally, we make real data applications for each one of the studied distributions.
