| 摘 要： | 利用纠偏思想,讨论定时截尾情形下Weibull分布的双参数的近似估计,并进行Monte-Carlo数值模拟试验.从模拟实验结果与Sirvanci提出的方法的模拟结果相比可以看出,纠偏法有时偏差较大,有时偏差较小.当产品数n比较大时,参数估计的精度还是令人满意的.分析表明,所给出的两参数估计方法是可行的.

| Abstract: | Approximate parameter estimation is provided and the Mante-Carlo simulation is done for two parameters Weibull distribution under type-I censoring by the thought of modifying.It is shown by comparing our simulation with the simulation provided by Sirvanci: The deviation sometimes is large and sometimes is small.However,the precision of the parameter estimation under a large amount of samples is all right.It is also shown by the analysis that the estimation method with two parameters is suitable. |
