GAM functions for Xpose 4

Description

These are functions for summarizing and plotting the results of the generalized additive model within Xpose

Usage

xp.akaike.plot(
  gamobj = NULL,
  title = "Default",
  xlb = "Akaike value",
  ylb = "Models",
  ...
)

xp.cook(gam.object)

xp.ind.inf.fit(
  gamobj = NULL,
  plot.ids = TRUE,
  idscex = 0.7,
  ptscex = 0.7,
  title = "Default",
  recur = FALSE,
  xlb = NULL,
  ylb = NULL,
  ...
)

xp.ind.inf.terms(
  gamobj = NULL,
  xlb = NULL,
  ylb = NULL,
  plot.ids = TRUE,
  idscex = 0.7,
  ptscex = 0.7,
  prompt = TRUE,
  ...
)

xp.ind.stud.res(
  gamobj = NULL,
  title = "Default",
  recur = FALSE,
  xlb = NULL,
  ylb = NULL
)

xp.plot(
  gamobj = NULL,
  plot.ids = TRUE,
  idscex = 0.7,
  ptscex = 0.7,
  prompt = TRUE,
  ...
)

xp.summary(gamobj = NULL)

Arguments

`gamobj`	A GAM object to use in the plot. IF null then the user is asked to choose from a list of GAM objects in memory.
`title`	A text string indicating plot title. If `NULL`, left blank.
`xlb`	A text string indicating x-axis legend. If `NULL`, left blank.
`ylb`	A text string indicating y-axis legend. If `NULL`, left blank.
`...`	Other arguments passed to the GAM functions.
`gam.object`	A GAM object (see `gam`.
`plot.ids`	Logical, specifies whether or not ID numbers should be displayed.
`idscex`	ID label size.
`ptscex`	Point size.
`recur`	If dispersion should be used in the GAM object.
`prompt`	Specifies whether or not the user should be prompted to press RETURN between plot pages. Default is TRUE.
`object`	An xpose.data object.

Value

Plots or summaries.

Functions

xp.akaike.plot(): An Akaike plot of the results.
xp.cook(): Individual parameters to GAM fit.
xp.ind.inf.fit(): Individual influence on GAM fit.
xp.ind.inf.terms(): Individual influence on GAM terms.
xp.ind.stud.res(): Studentized residuals.
xp.plot(): GAM residuals of base model vs. covariates.
xp.summary(): Summarize GAM.
