Purpose – To present the bootstrap procedure to correct biases in maximum likelihood estimator of mean time to failure (MTTF) and percentiles in a Weibull regression model. Design/methodology/approach – A reliability model is described by a Weibull regression model with parameters being estimated ...

The unbiased predictor of linear predictable variable and its relationship to unbiased estimator of mean vector in finite populations are investigated. 研究了有限总体均值向量的无偏估计和线性可预测变量的无偏预测之间的关系,利用分块矩阵广义逆直接对加权风险函数进行分解,提出了一种由均值向量的无偏估计来构造...
We propose an alternative Rao–Blackwell type unbiased estimator. We show that the family of distributions of the sufficient statistic is not complete, and there exist infinitely many unbiased estimators of the mean vector and none has uniformly minimum variance. However, when restricted to truncation...
