WebMixed GAM Computation Vehicle with GCV/AIC/REML smoothness estimation and GAMMs by REML/PQL Description. mgcv provides functions for generalized additive modelling (gam and bam) and generalized additive mixed modelling (gamm, and random.effects).The term GAM is taken to include any model dependent on unknown …
WebFunctions used for the definition of tensor product smooths and interactions within gam model formulae. te produces a full tensor product smooth, while ti produces a tensor product interaction, appropriate when the main effects (and any lower interactions) are also present. The functions do not evaluate the smooth - they exists purely to help set up a … WebThese data have subsequently been synthesized into subjective Habitat Suitability Index (HSI) models. The models are based on suitability indices formulated for variables found to affect the llfe cycle and survlval of each species. The models are designed to be modified to evaluate specific habitat alterations using the HSI model building ...
