Design Effects for linear regression Models
Ph.D. course: Regression models. Linear effects. Approaches
... If we compose the linear predictor of several such spline terms: LP i = a + bx i + b 1 x + i1 + ... + b 4 x + i4 we get a broken linear function (Figure). The parameter b j is the change of slope at ...
