I am running a model Y=beta0+beta1*X1+beta2*X2+beta3*X3+...+betan*Xn. After running the model command, Stata automatically drops some covariates because of colinearity. I want to get the final covariates which are left in the model. What I did is something like this.
. reg y x1 x2 x3 x4 x5
. matrix beta = e(b)
. global covariates : colfullnames beta
Suppose x2 was dropped because of colinearity.
It gives me a global as
y:x1 y:x3 y:x4 y:x5 y:_cons
How can I remove "y:" in the global so that I have a global as "x1 x3 x4 x5 _cons"?

Thank you very much!
