Line for the server...


"I remember doing this long time ago but I forgot the command."

What you remember is probably -h xi-, "Summary of controlling the omitted
dummy" where you tell Stata which dummy to drop because you and Stata know
beforehand that there must be collinearity...

Subject: st: Collinearity

I am running a Logit model with 12 variables, the results says that variable
x was dropped because of collinearity. is there any command that can help
identify the other variable with wich x is correlated, the reason I am
asking for this is that x is an important variable and I prefer to drop
another variable and keep x. I remember doing this long time ago but I
forgot the command.


Many thanks,

Ismail
