Gamma distribution Gamma(a,b)(in which:a>0,b>0) is always used as a prior distribution of Bayesian exponential distribution reliability growth model. Different value of a and b will make considerable difference in evaluating results.

• Gamma分布Gamma(a ,b) (其中a >0 ,b>0 ) ,通常用来作指数分布Bayes可靠性增长模型的先验分布 ,参数a和b的不同 ,将使可靠性增长试验的评估结果有很大的差异。
