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. Instead, it shows
"NA":
And what package is the `stdCoeff` function in? If we don't have a
reproducible example, it's very hard to help.
What does calling the summary function on your lm object give you?
(Intercept)
