Line 32: \end{align}</math>. Therefore, since <math>\mathbf{Ax}</math> is on the column space of <math>\mathbf{A}</math>, the projection matrix, which maps <math>\mathbf{b}</math> onto <math>\mathbf{x}</math>, is ~~just <math>\mathbf{A}</math>, or~~ <math>\mathbf{A}\left(\mathbf{A}^\textsf{T}\mathbf{A}\right)^{-1}\mathbf{A}^\textsf{T}</math>. == Linear model == Line 110: [[Category:Regression analysis]] [[Category:Matrices (mathematics)]]
