[R] mutlicollinearity and MM-regression

[Carsten.Colombier@efv.admin.ch]

Dear R users,

Usually the variance-inflation factor, which is based on R^2, is used as a
measure for multicollinearity. But, in contrast to OLS regression there is
no robust R^2 available for MM-regressions in R. Do you know if an
equivalent or an alternative nmeasure of multicollinearity is available for
MM-regression in R?


With best regards,
