Indeed. And the use of generalised linear models as
a way of avoiding the consequent transformation bias
has been urged by many people. There is a very good
expository paper by
Lane, PW. 2002. Generalized linear models in soil science.
European Journal of Soil Science 53: 241-251.
Don't worry about the soil science flavour, which
is not strong.
