摘要：

in the linear regression method for estimating parameters of a Weibull distribution, multiple flaw distributions may be further evidenced by derivation form the linearity of data from a single Weibull distribution. In this paper, a new technique of estimating multiple Weibull parameters is conducted, compared to commonly used regression probability estimator. Crown Copyright (C) 2009 Published by Elsevier Ltd.
