aIn each panel, a vertical line is placed at the end of the indices for 71 main effects, and 2 horizontal lines are placed at the maximum absolute standardized differences; crosses (x) mark the indices j corresponding to 188 nonzero estimates of γj for π^RML and 32 nonzero estimates of γj for π^RCAL1. (d) Fitted PSs π^RML (Xi), π^RCAL1 (Xi) in the treated sample {i: Ti = 1, i = 1,…, n}.
