Hi all,

I am running the sbsingle command to test for a structural break with unknown break date.
Code:
reg y L1.y x z
estat sbsingle
I get the following error code:
Code:
postestimation cannot continue due to collinear variables
r(198);
However, if I check the VIF scores on all variables implemented into the regression, there is no indication of colinearity.
What am I doing wrong? I am using STATA 15.1
Best,

Marcel
