On a family of discrete log-symmetric distributions
Abstract
The use of continuous probability distributions has been widespread in
problems with purely discrete nature. In general, such distributions are not
appropriate in this scenario. In this paper, we introduce a class of discrete
and asymmetric distributions based on the family of continuous log-symmetric
distributions. Some properties are discussed as well as estimation by the
maximum likelihood method. A Monte Carlo simulation study is carried out to
evaluate the performance of the estimators, and censored and uncensored data
sets are used to illustrate the proposed methodology.
