Web11.2 Generalized additive mixed effect models (GAMMs) in a nutshell. Generalized additive mixed effect models (GAMMs) are a type of statistical model that combines … Webmgcv also provides a routine 'gamm' for generalized additive mixed model estimation by PQL and 'bam' for estiamtion of GAMs for very large datasets. The linear preditor of a model in `mgcv' can depend on any bounded linear functional of a smooth, via a summation convention used in model specification. This allows, e.g. scalar-on-function ...

WebIn R, a family specifies the variance and link functions which are used in the model fit. As an example the “poisson” family uses the “log” link function and “ μ μ ” as the variance function. A GLM model is defined by both the formula and the family. GLM models can also be used to fit data in which the variance is proportional to ... WebDescription.
