Vector Generalized Additive Models

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1996
SUMMARY Vector smoothing is used to extend the class of generalized additive models in a very natural way to include a class of multivariate regression models. The resulting models are called ‘vector generalized additive models‘. The class of models for which the methodology gives generalized additive extensions includes the multiple ...

Using flexible regression models for calculating hospital’s production functions

BMC Health Services Research, 2020
Background The relative lack of flexibility of parametric models has led to the development of nonparametric regression techniques based on the family of generalized additive models. However, despite the potential advantages of using Generalized Additive
