摘要
在熵损失下得到了尺度参数的最小风险同变估计的精确形式,并讨论了一类形如[cTα+d]-1的估计的容许性;考虑形状参数的估计方法,进一步给出了熵损失下定数渐进删失Weibull分布两参数都未知时尺度参数的估计.
Firstly,an explicit form of the minimum risk equivaria nt estimator of the scale parameter was obtained,and the admissibility of a cla ss of estimators of the form -1 was discussed.Then the es timation methods of the shape parameter were considered,further,the estimator of the scale parameter was proposed under entropy loss function based on progres sive Type-Ⅱ censoring scheme when both the parameters were unknown.
