This is a plot of population conditional weighted residuals (CWRES) vs the independent variable (IDV), a specific function in Xpose 4. It is a wrapper encapsulating arguments to the xpose.plot.default function. Most of the options take their default values from xpose.data object but may be overridden by supplying them as arguments.

Usage

cwres.vs.idv(object, abline = c(0, 0), smooth = TRUE, ...)

Arguments

object

An xpose.data object.

abline

Vector of arguments to the panel.abline function. No abline is drawn if NULL.

smooth

A NULL value indicates that no superposed line should be added to the graph. If TRUE then a smooth of the data will be superimposed.

...

Other arguments passed to link{xpose.plot.default}.

Value

Returns an xyplot of CWRES vs IDV.

Details

Conditional weighted residuals (CWRES) are plotted against the independent variable, as specified in object@Prefs@Xvardef$idv.

Conditional weighted residuals (CWRES) require some extra steps to calculate. See compute.cwres for details.

A wide array of extra options controlling xyplots are available. See xpose.plot.default and xpose.panel.default for details.

Examples

## Here we load the example xpose database 
xpdb <- simpraz.xpdb

## A vanilla plot
cwres.vs.idv(xpdb)


## A conditioning plot
cwres.vs.idv(xpdb, by="HCTZ")
