Fig. 1From: Sample selection bias with multiple dependent selection rules: an application to survey data analysis with multilevel nonresponseBoxplots of the estimated regression coefficients of \(\beta _0\) and \(\beta _1\) with normality assumption from 500 simulation runs. Methods are the bivariate selection model using two-step and one-step methods, BSM (two-step) and BSM (one-step), respectively, univariate selection model using one-step method, USM (one-step), and complete case analysis (CC), i.e., data after deleting nonresponse casesBack to article page
