interacting variables in a formulae in R
Dear R Mailing Subscribers,
I just have a question of how R handles interacting variables in model
creation using glm for instance.
if I write :
>>
model=glm(solution~descriptor1+descriptor2+descriptor3,family=binomial(link="logit"))
I should end up with coefficients for a logistic model that I can introduce
easily in the mathematical form of such a model (weighted sum of these
descriptors).
But how do I have to interpret what R does with interacting terms, lik...
