cubshevisual {CUB}

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,...)

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.

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.
