Abstract:

There are a lot of incomplete data and non failure data in the real engineering. The mean ranks of the incomplete fatigue life data and the non failure data are presented respectively. And the parameter estimation methods of the 3 Parameter Weibull Distribution and the log Gauss Distribution, which the incomplete fatigue life data follows, are proposed respectively. At last, two examples are given.

Key words: incomplete data, mean rank, parameter estimation
