*设因变量y;截断点0.5与-0.5;自变量x1-xn;g是0-1变量。检验两组回归中x1系数的差别
tob y x* if g, ll(-.5) ul(.5)
est sto a
tob y x* if !g, ll(-.5) ul(.5)
est sto b
suest a b
test [a_model]x1=[b_model]x1
请问大神们,,用空间Tobit,做suest,显示unable to generate scores for model a
suest requires that predict allow the score option
r(322);
但是,用tobit可以做出结果。是不是suest不支持空间tobit?
