CUB (version 1.1.5)

cubshevisual: Plot an estimated CUB model with shelter

Description

Plotting facility for the CUB estimation of ordinal responses when a shelter effect is included

Usage

cubshevisual(ordinal,shelter,csiplot=FALSE,paiplot=FALSE,...)

Value

For a CUB model with shelter fitted to ordinal, by default it returns a plot of the estimated \((1-\pi, 1-\xi)\) as a point in the parameter space, labeled with the estimated shelter parameter \(\delta\). Depending on csiplot and paiplot and on desired output, \(x\) and \(y\) coordinates may be set to \(\pi\) and \(\xi\), respectively.

Arguments

ordinal

Vector of ordinal responses

shelter

Category corresponding to the shelter choice

csiplot

Logical: should \(\xi\) or \(1-\xi\) be the \(y\) coordinate

paiplot

Logical: should \(\pi\) or \(1-\pi\) be the \(x\) coordinate

...

Additional arguments to be passed to plot() and text(). Optionally, the number m of ordinal categories may be passed: this is recommended if some category has zero frequency.

Details

It represents an estimated CUB model with shelter effect as a point in the parameter space with shelter estimate indicated as label.
