multicub {CUB} | R Documentation |
Joint plot of estimated CUB models in the parameter space
Description
Return a plot of estimated CUB models represented as points in the parameter space.
Usage
multicub(listord,mvett,csiplot=FALSE,paiplot=FALSE,...)
Arguments
listord |
A data matrix, data frame, or list of vectors of ordinal observations (for variables with different number of observations) |
mvett |
Vector of number of categories for ordinal variables in |
csiplot |
Logical: should |
paiplot |
Logical: should |
... |
Value
Fit a CUB model to list elements, and then by default it returns a plot of the estimated
(1-\pi, 1-\xi)
as points 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.
Examples
data(univer)
listord<-univer[,8:12]
multicub(listord,colours=rep("red",5),cex=c(0.4,0.6,0.8,1,1.2),
pch=c(1,2,3,4,5),xlim=c(0,0.4),ylim=c(0.75,1),pos=c(1,3,3,3,3))
