xp.incl.index.cov.ind: Individual inclusion index

Description

This function will generate a plot of individual inclusion indexes for a specific covariate, which can be used to identify influential individuals for inclusion of that covariate. The index for an individual is calculated as the observed number of inclusions of that individual when the specific covariate was included minus the expected number of inclusions (based on the total bootstrap inclusions), divided by expected.

Usage

xp.incl.index.cov.ind(bootgam.obj = NULL, boot.type=NULL, cov.name = NULL, 
                      main = NULL, ylb = "ID", 
                      xlb = "Individual inclusion index", ...)

Arguments

bootgam.obj
A bootgam or bootscm object.
boot.type
Either "bootgam" or "bootscm". Default is NULL, which means the user will be asked to make a choice.
cov.name
The name of the covariate for which to create the plot.
main
The title of the plot.
xlb
The label for the x-axis.
ylb
The label for the y-axis.
...
Additional plotting parameters.

Value

  • A lattice plot object is returned.
