Joerg,
If you are modeling the dependent variable, why does its
right-skewness matter? Much of the apparent right-skewness may be due
to effects of predictors in your model.
The distribution that your model uses for the individual proportions
does matter. Nick makes a good point about continuous proportions,
but your proportions are likely to be binomial, with variation in both
p and n.
