Gam smoothing

In statistics, a generalized additive model (GAM) is a generalized linear model in which the linear response variable depends linearly on unknown smooth functions of some predictor variables, and interest focuses on inference about these smooth functions. GAMs were originally developed by Trevor Hastie and Robert … See more The original GAM fitting method estimated the smooth components of the model using non-parametric smoothers (for example smoothing splines or local linear regression smoothers) via the backfitting algorithm. … See more As with any statistical model it is important to check the model assumptions of a GAM. Residual plots should be examined in the same way as … See more Overfitting can be a problem with GAMs, especially if there is un-modelled residual auto-correlation or un-modelled overdispersion. Cross-validation can be used to detect and/or reduce overfitting problems with GAMs (or other statistical methods), and … See more Many modern implementations of GAMs and their extensions are built around the reduced rank smoothing approach, because it allows well founded estimation of the smoothness … See more Backfit GAMs were originally provided by the gam function in S, now ported to the R language as the gam package. The SAS proc GAM also … See more When smoothing parameters are estimated as part of model fitting then much of what would traditionally count as model selection … See more • Additive model • Backfitting algorithm • Generalized additive model for location, scale, and shape (GAMLSS) See more WebJul 30, 2015 · The GAM models where smoothing parameters were automatically selected with REML perform better than the model where we used a flat smoothing parameter of 0.6 across all variables (which tends …
