Webb15 feb. 2024 · Shape-constrained generalized additive models (or simply SC-GAMs, Pya and Wood, 2014) are based on the same statistical framework as GLMs and GAMs regression methods, but they allow us to incorporate monotonicity and concavity shape-constraints in the component functions of the linear predictor of the GAMs. WebbA framework is presented for generalized additive modelling under shape constraints on the component functions of the linear predictor of the GAM. We represent shape constrained model components by mildly non-linear extensions of P-splines.
