Abstract:
|
We discuss the conditional distribution of a geometric random variable, where the parameter itself has a beta distribution. The mixture of these distributions is referred to as the beta-geometric distribution (BGD). We obtain a generalized expression for the moments, with a recursion noted in the probability function. The application of the distribution in fecundability and manpower or contractual modeling is investigated. We obtain estimates of the survival and hazard functions of the fitted model. The method of the maximum likelihood estimates is discussed, and estimates of the parameters of a set of data are obtained.
