Hello all,
I am running a meta analysis on WTP for wind energy. I am using Stata 16. I use the command meta regress with option fixed. Now I need to check for multicollinearity. For regular OLS with vce(cluster var) and aweight[inverse standard error for precision] I use the vif command. Unfortunately in the case of meta regress vif is just possible with the uncentered option, but I don't know if this is appropriate or how to interpret the results. Does anybody have a suggestion how I could test for multicollinearity in this case? I would be very grateful.
