I am curious what the formula for B values is when you have more than two variables. While I know any software can easily tell me the answer, I do not want to use it to figure out the B values, I want the actual equation. Everywhere I look I get equations like the following:
I cannot find any images or information on equations for the b values when there is more than two variables. I am also interested in how the formulas change between amount of variables. If anyone can tell me or point me to where I can find this information I would be grateful.
