Estimation of the Slope and Analysis of Covariance When the Concomitant Variable is Measured with Error
伴随变量存在测量误差时的斜率估计与协方差分析
Estimators of the slope for models with errors of observation in the explanatory variable are investigated. Estimators are developed which have a bias of smaller order and smaller mean square error than the common estimator. These estimators of slope are utilized in the analysis of covariance where the concomitant variable is measured with error. The procedure is applicable for any number of treatments or determinations per treatment. The computations are illustrated with an…
