加权对数秩估计函数已成为截尾线性回归模型或加速失效时间模型的标准估计方法。从统计学上来说,定义为一致根的估计量具有相当差的计算特性,因为估计函数既不是连续的,通常也不是单调的。我们通过渐近引导牛顿算法提出了一种计算高效的估计器,其中审查分位数回归方法被定制以产生初始一致估计和极限估计函数的一致导数估计。我们还通过三明治方差估计的新建议开发了快速区间估计。所提出的估计器渐近等效于一致根估计器,并且在实际大小的样本中几乎无法区分。然而,仅对于点估计,计算时间通常会减少两到三个数量级。提供了临床应用的插图。
Weighted log-rank estimating function has become a standard estimation method for the censored linear regression model, or the accelerated failure time model. Well established statistically, the estimator defined as a consistent root has, however, rather poor computational properties because the estimating function is neither continuous nor, in general, monotone. We propose a computationally efficient estimator through an asymptotics-guided Newton algorithm, in which censored quantile regression methods are tailored to yield an initial consistent estimate and a consistent derivative estimate of the limiting estimating function. We also develop fast interval estimation with a new proposal for sandwich variance estimation. The proposed estimator is asymptotically equivalent to the consistent root estimator and barely distinguishable in samples of practical size. However, computation time is typically reduced by two to three orders of magnitude for point estimation alone. Illustrations with clinical applications are provided.
