As others have noted a general solution to this problem is impossible,
probably because it's ill-posed and thus there's no way of generating
a definitive answer short of narrowing it substantially, but one
simple thing that many folks do is use semi-partial correlations. The
square of a semi-partial correlation is the R^2 increment obtained by
adding this variable, conditional on all others in the model. In Stata
you can get this using -pcorr-.
