Best ResponseYou've already chosen the best response.0yeah i understand that but how would you know which type of regression to use?

Best ResponseYou've already chosen the best response.0I think you just try every single one, and the one that goes through the most points will be the one to use, because calculator would approximate all equations. So just try all three, and whichever one comes closest to as many points as possible will be the one to use.
