Abstract

GOMEZ, YOLANDA M.; BOLFARINE, HELENO  and  GOMEZ, HÉCTOR W.. A New Extension of the Exponential Distribution. Rev.Colomb.Estad. [online]. 2014, vol.37, n.1, pp.25-34. ISSN 0120-1751.  https://doi.org/10.15446/rce.v37n1.44355.

The present paper considers an extension of the exponential distribution based on mixtures of positive distributions. We study the main properties of this new distribution, with special emphasis on its moments, moment generator function and some characteristics related to reliability studies. We also discuss parameter estimation considering the maximum likelihood and moments approach. An application reveals that the model proposed can be very useful in fitting real data. A final discussion concludes the paper.

Keywords : Exponential distribution; Mixtures of distribution; Likelihood.
