摘    要:本文考虑了长度偏差右删失数据下均值剩余寿命模型的统计推断.当截断变量满足平稳性假设时,长度偏差右删失数据比左截断右删失数据具有更多的信息.为了提高参数估计的效率,我们在估计方程构造中添加了额外信息,通过组合方法获得了新的估计.模拟研究的结果也表明,组合估计方程的方法比仅考虑左截断右删失数据的方法更有效,结果表现更好.

Abstract:We use the mean residual lifetime function to analyze the length biased data with right censorship. When the truncated time satisfies the stationarity assumption, the left truncated and right censored data turns to be the length-biased data and has special property. In order to improve the efficiency of the estimators, we use the combining estimating equation method that incorporates the additional information about length-biased sampling scheme to do the inference. The simulation shows that the combining estimating equation method performs better than the naive method which regards length-biased data as the left truncated data.
Keywords:combining information  mean residual lifetime model  length-biased data  right censorship  counting process
