I performed a good dozen searches but didn't find the answer, did they change the initial skill values from fallout 3? 2+(Stat x 2)+(Luck/2)
Or is it something different?

It is the same as it was in Fallout 3.

2 + (SPECIAL x 2) + (Luck / 2)

Thanks, I was curious and to my surprise it wasn't on the wikia yet.[I've fixed that now]
