Yeah, even many books are offered, this book can steal the reader heart so much. Since our model will usually contain a constant term, one of the columns in the X matrix will contain only ones. (1). I have the following equation: B-hat = (X'X)^-1(X'Y) I would like the above expression to be expressed as B-hat = HY. where M = I n X(X0X) 1X 0.
