Hello,
I have got a linear model that looks like this:
lm(criterion ~ variable.A*variable.a + variable.B*variable.b + variable.C
, summary should also give them to you.

Hello,
I have got a linear model that looks like this:
lm(criterion ~ variable.A*variable.a + variable.B*variable.b + variable.C
*variable.c)
The output computed with stdCoeff() seems to be all right, but it does not show
the coefficients of the interaction of the first pair of variables.

Jennifer,
Please provide us more information. It would be helpful to see the
actual code you ran along with the actual output. How did you get the
values that your included with your email message? Did you get the
values using the summary function, e.g.
fit0-lm(y~x+sex+x*sex)
summary(fit0)
