Predicted y

WebSay I have a set of points Y and I want to accuratly predict the values of Y by using three variables X1,X2,X3. Hence my equation is. Y=intercept + C1*X1 + C2*X2 + C3*X3. After performing linear regression I get my values of C1,C2,C3 and the intercept. For every value of X1,X2,X3 I have a new point Y' that is supposed to be as close as possible ...
