Fixed horrible bug discovered by Aaron Rendahl where when some variable names were substrings of other variable names not all models were searched.
This could have been avoided if I had remembered the famous quote by Jamie Zawinski: “Some people, when confronted with a problem, think ‘I know, I'll use regular expressions.’ Now they have two problems.”
Now AICc == Inf when n <= p + 1.
Now error when AIC(out) is when out is output
of R function glm.
Added graphical models. Now can search only over graphical models.
First submission to Github. Does all hierarchical models.
