摘要
针对正态分布场合下无失效数据的情形,利用最小二乘估计,加权最小二乘估计和模糊加权最小二乘估计三种方法,给出正态分布参数和可靠度的计算方法.
Aimed at the case of zero failure data with normal distribution and by using three methods： least squares estimation, weighted least squares estimation and fuzzy weighted least squares estimation, an evaluation method of normally distributed parameters and their reliability was proposed.
