<p>In the calculation of regression coefficients,
 \(\mathbf{B}_{(-I)} = (\mathbf{X}_{(-I)}^{T} \mathbf{X}_{(-I)})^{-1} \mathbf{X}_{(-I)}^{T} \mathbf{Y}_{I}\) are the estimated
 coefficients
 when the cases indexed by \(I\) have been removed. The corresponding residuals are
 \(\mathbf{E}_{(-I)} = \mathbf{Y}_{(-I)} - \mathbf{X}_{(-I)} \mathbf{B}_{(-I)}\).</p>
