WebThe RegressionLinear Predict block predicts responses using a linear regression object ( RegressionLinear ). Import a trained regression object into the block by specifying the name of a workspace variable that contains the object. The input port x receives an observation (predictor data), and the output port yfit returns predicted responses ... WebRidge regression addresses the problem of multicollinearity by estimating regression coefficients using. β ^ = ( X T X + k I) − 1 X T y. where k is the ridge parameter and I is the identity matrix.
