gammar

We deduce the maximum likelihood and Bayes estimates of these parameters when the joint survival function obeys the two dimentions exponential distribution, while in Bayes approach, it is assumed that the unknown parameters have Gammar prior distributions.

在Bayes估计中，我们假定未知参数的先验分布为伽马分布，两章都通过数据模拟对极大似然估计和Bayes估计这两种方法进行了比较。
