Hazards regression analysis for length-biased data
长度偏倚数据的风险率回归分析
Length-biased sampling is frequently a convenient technique for the collection of positive-valued or lifetime data. Estimation porocedures based on pseudo-likelihood are developed under the proportional hazards model for length-biased data. Bias-adjusted risk set sampling is used for the construction of the pseudo-likelihood and the risk set sampling is rephcated to improve estimation performance. The average of the resulting likelihood estimators is taken as the estimator…
