Hi
I'm working on a fleet glm and I'm currently testing interactions. I have a couple of queries regarding this topic...
1. In some cases I am getting a significant interaction between two factors even though the simple factors themselves are not significant. Does this make sense or is it plausible for these types of interactions to form part of a good model.
2. Should you test an interaction for consistency. Given my dataset isn't very large this is not very feasible in a lot of interactions but just wanted to get peoples opinions on this.
Thanks
