摘要： 研究了反高斯分布环境因子估计。根据指数分布和对数正态分布环境因子的定义及数据折算与综合的方便,给出了反高斯分布环境因子的定义。据此定义,用经典方法和贝叶斯方法推证了环境因子的上、下限,并给出了一些近似式以便于计算。实例计算结果较令人满意。

Abstract: In this paper,environmental factor estimation for the inverse Gaussian distribution with two parameters is studied and two definitions of environmental factors with inverse Gaussian distribution are proposed.Based on the above definition,the Bayesian confidence limits of the inverse Gaus- sian environmental factor are also given respectively using non-informa- tive reference prior distribution as well as the natural conjugate prior dis- tribution.An application of these results is provided.
