I tried to do a OLS linear regression and got the following error message the end of the output:
"2 The smallest eigenvalue is 1e-25. This might indicate that there are strong multicollinearity problems or that the design matrix is singular."
I thought regression was supposed to solve/account for multicollinearity. Should I do PCA before regression and try this again?
How do I solve this error message? Is it even significant?
EDIT: Took advice from commenter.
