multiple regression help
Hi all, im having some trouble getting my head around this question, I dont want to seem like someone just gettin them to do my work, so guidence along the way to help me do it is welcome!
I've got some idea that the first question that magnitude is just size, sign is positive or negative, but i dont really know how to expand on the answer.
For the next im not to sure why you use two dummy variables, is it because you jsut want them to have values of 0 or 1, a kind of yes or no?
The others im very stuck on! So help and guidence would be greatly appreciated. If these forums do reputation, id gladly distribute for your time :)
