| 摘 要： | 研究了二参数伽玛分布环境因子的估计。根据伽玛分布的特点,指数分布环境因子的定义,并考虑数据折算的方便,给出了伽玛分布环境因子的定义。根据此定义,用经典方法、贝叶斯方法和Fiducial 方法推证了环境因子的上、下限,并给出了一些近似式。

| Abstract: | Environmental factor estimation for the gamma distributionwith two parameters is studied here.In consideration of the characteristicsof the gamma distribution and the definition of environmental factors forthe exponential distribution and the convenience of data converting,the de-finition of environmental factors for the gamma distribution is proposed.In according to this definition,lower and upper confidence limits of environ-mental factors are derived by classical,Bayesian and Fiducial methods,andsome approximate confidence limits are also given.A practical example isprovided. |
