|Title:||An extended Birnbaum-Saunders model and its application in the study of environmental quality in Santiago, Chile|
|Abstract:||In this article, we introduce, characterize and apply an extended version of the Birnbaum-Saunders model based on the Mudolkar-Hutson skew distribution. This model is appropriated for describing phenomena involving accumulation of some type, as is the case of environmental contamination. Specifically, we find the density, distribution function, and moments of the new model. In addition, we derive several properties and transformations related to this distribution. Furthermore, we propose an estimation method for the parameters of the model. Moreover, we conduct a study of its hazard rate focuses in environmental analysis. A computational implementation in R language of the obtained results is discussed. Finally, we present two examples with real data from environmental quality in Chile that illustrate the proposed methodology.|
