cubshevisual function

Plot an estimated CUB model with shelter

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

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.

Returns

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.

Details

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