I am using the -coldiag2- command to test for multicollinearity among a
set of independent variables.  However, my regression model is -ologit-
(and sometimes -oprobit-).  I am not sure if adding the constant term,
a default option for coldiag2, is appropriate, since that is
specifically designed for OLS.  A look at Greene was not particularly

Could anyone could advise me on whether I should run coldiag2 with or without
the constant in this case? Any further citations or references would be
great, too. 

Thank you,

Camille Antinori
