Regression and Y hat question!!!!!!!!!!!!!?

Question

I have a regression equation,
One response and 3 regressors.
How do i figure out Y-hat?

Answer 1

Y hat is what your regression equation gives for a set of three inputs.

You regression produced 4 coefficients, usually called betas: Y_hat is a linear combination of regressors of the form:

Y_hat = b0 + b1*r1 + b2*r2 + b3*r3
