Dear R-helpers,
In the case of two categorical factors, say a and b, once I have
fixed the constrasts, the model matrix is set according to these
contrasts with "lm", and the t-tests for the significance of the
parameters provided by "summary" indeed concern the comparison of the
model with ea
permutations smaller than (N1+N2)/(N1!*N2!), the result will generally
be different.
I would be very grateful if someone could provide me an explanation
for the samr choice of the permutations.
Thanks for your help,
Isabelle
