[Chaimaa]

Hello guys, could anyone plz explain form me what's the difference between multinomial logistic regression and traditional regression?

I have used a method called elastic-net as the response variables are in discrete format, but i get confused if this method is suitable or not or i have to use a multinomial logistic regression.

i appreciated any help!
