Omitted variable test results

Method	Judgment standard	Actual calculation result	Whether it passes or not
(1)	β^*(R_max,δ) $\in$ [−0.131,0.161]	β^*(R_max,δ) = 0.015	Pass
(2)	δ ≥ 1 or δ < 0	δ = 24.483	Pass

Note(s): This table shows the regression results for the omitted variables test: Line (1), δ test; Line (2), β^*(R_max, δ) test
