摘要：
The parameter estimation method of best linear unbiased estimation is a very useful method for Weibull distribution, when sample size is less than 25 and complex procedure is related. Based on the integral function transformed from infinite interval to limited interval, and the adaptive Gauss integral method is introduced, a fast calculation method is presented for the mean value and variance of order statistics. Furthermore an optimized calculation method of best linear unbiased estimation is proposed for Weibull distribution product. The method can be used in sample size more than 50, which a high precision calculation method is offered for reliability data analysis.
