I am guessing that we have different definitions of what a beta
coefficient is. As I understand the terminology a beta coefficient
involves both standardizing the
independent/explanatory/regressors/right-hand-side/x-variables _and_
the dependent/explained/left-hand-side/y variable. So beta
coefficients have everything to do with the (first two) moments of
your dependent variable. Now it may or may not make sense to only
standardize your independent variables, but that would not result in
beta coefficients as I understand it.
