The two‐sample linear regression model with interval‐censored covariates
针对协变量为区间删失数据、但存在第二个独立样本精确测量协变量的情况，提出一种半参数有效估计量，用于线性回归模型的系数估计，并以收入与身体质量指数的关系为例展示其应用。
Summary There are surveys that gather precise information on an outcome of interest, but measure continuous covariates by a discrete number of intervals, in which case the covariates are interval censored . For applications with a second independent dataset precisely measuring the covariates, but not the outcome, this paper introduces a semiparametrically efficient estimator for the coefficients in a linear regression model. The second sample serves to establish point identification. An empirical application investigating the relationship between income and body mass index illustrates the use of the estimator.
