The Generalized Additive Model for Location, Scale and Shape (GAMLSS) is an approach to statistical modelling and learning. GAMLSS is a modern distribution-based approach to (semiparametric) regression. A parametric distribution is assumed for the response (target) variable but the parameters of this distribution can vary according to explanatory variables using linear, nonlinear or smooth functions. In machine learning parlance, GAMLSS is a form of superv… WebAug 1, 2024 · GAMLSS package in R. Accompanying documentation in the current GAMLSS help ﬁles, (see also http://www.gamlss.org/).
