plotdiag.deviance.residuals {forsearch}R Documentation

Plot Diagnostic Statistics Of Deviance Residuals

Description

Plot output from forsearch_glm to show change in deviance residuals or augmented deviance residuals, either of which can be squared, as the number of observations in the forward search procedure increases. Save plot in folder containing working directory.

Usage

plotdiag.deviance.residuals(forn, squared = FALSE, augmented=TRUE, hilos = c(1, 0), 
maintitle="Put main title here", subtitle="Put subtitle here", caption="Put caption here", 
wmf= "Put_graph_title_here", Cairo=TRUE,printgraph=TRUE,
legend = "Dummy legend name", verbose = TRUE)

Arguments

forn

Name of forward search output file

squared

TRUE causes residuals to be squared before plotting

augmented

TRUE causes graphing of augmented deviance residuals, see Details

hilos

Number of observations having high and number having low values of residuals to identify. No low values are identified for squared residual plot

maintitle

Main title of plot

subtitle

Subtitle of plot

caption

Caption of plot

wmf

File name of stored plot; omit ".wmf"

Cairo

TRUE causes use of Cairo graphics

printgraph

TRUE causes graph to print to file and closes device

legend

Legend title

verbose

If TRUE, indicates beginning and end of function

Details

We reserve the use of the term 'Deviance residuals' to deviance residuals of the observations that were used to create the model fit, and use the term 'Augmented deviance residuals' to refer to deviance residuals of all available observations. The latter are created by predicting the fit of the model to all observations.

Value

Process and plot changes in deviance residuals or squared deviance residuals from forsearch_glm
