摘要
A five-parameter extended fatigue life model called the McDonaldBirnbaumSaunders (McBS) distribution is proposed. It extends the BirnbaumSaunders and beta BirnbaumSaunders [G.M. Cordeiro and A.J. Lemonte, The -BirnbaumSaunders distribution: An improved distribution for fatigue life modeling. Comput. Statist. Data Anal. 55 (2011), pp. 14451461] distributions and also the new KumaraswamyBirnbaumSaunders distribution. We obtain the ordinary moments, generating function, mean deviations and quantile function. The method of maximum likelihood is used to estimate the model parameters and its potentiality is illustrated with an application to a real fatigue data set. Further, we propose a new extended regression model based on the logarithm of the McBS distribution. This model can be very useful to the analysis of real data and could give more realistic fits than other special regression models.
