Issue Date: | 2016 | Journal: | Communications in Statistics Part B: Simulation and Computation | Abstract: | In this article, we have developed a Poisson-mixed inverse Gaussian (PMIG) distribution. The mixed inverse Gaussian distribution is a mixture of the inverse Gaussian distribution and its length-biased counterpart. A PMIG regression model is developed and the maximum likelihood estimation of the parameters is studied. A dataset dealing with the number of hospital stays among the elderly population is analyzed by using the PMIG and the PIG (Poisson-inverse Gaussian) regression models and it has been shown that the PMIG model fits the data better than the PIG model. | URI: | http://hdl.handle.net/10553/42445 | ISSN: | 0361-0918 | DOI: | 10.1080/03610918.2014.925924 | Source: | Communications in Statistics: Simulation and Computation[ISSN 0361-0918],v. 45, p. 2767-2781 |
