Calculates the Cook's distance for Generalized Additive Mixed Models (GAMM)

Description

cooks_dist_gamm is a helper function for model_gamm and plot_diagnostics and calculates the Cook's distance for objects of class 'gamm'. The Cook's distance D is a leave-one-out deletion diagnostics to measure the influence of each observation. The generic cooks.distance function does not work on the class 'gamm'.

Usage

cooks_dist_gamm(gamm_model)

Arguments

gamm_model

The ‘gam‘ sublist from a model object of class gamm.

Value

The function returns a numerical vector of the same length then the data used for the GAMM fitting, with one D value for each IND observation.

See Also

plot_diagnostics, model_gamm

Examples

# Using a model of the Baltic Sea demo data
cooks_dist_gamm(gamm_model = model_gamm_ex$model[[49]]$gam)
