Hey, great video! I used the fracreg probit command and i want to test if there is a u-shape now but the utest command doesn't work after this regression, it only works after using xtreg regression. Do i have to use xtreg to test for a u-shape?
@louisa9783 Generally, you can rely on the marginal effects analysis. The utest command is essentially a variant of the marginal effects analysis and can serve as a complementary test.
