摘要
讨论对数正态分布场合有非常数尺度参数恒加试验的参数估计,由最小均方误差准则导出基于完全样本恒加试验的点估计和近似区间估计.
We discusses the parameter estimation of the stress accelerated life test under the lognormal distribution. New point estimators and approximate confidence interval estimation are derived by the minimum mean square error rule. The analysis results show that the new estimators and approximate confidence interval estimation are more effective.
