It represents an estimated CUB model as a point in the parameter space with some useful options.
For a CUB model fit to ordinal
, by default it returns a plot of the estimated
(1-\pi, 1-\xi)
as a point in the parameter space. Depending on csiplot
and paiplot
and on desired output, x
and y
coordinates may be set to \pi
and \xi
, respectively.
