Description Usage Arguments Author(s) See Also Examples
Plot function for a MultOrd
object. Plots show coefficients of the explanatory variables, both with repect to location and response styles.
The coefficient pairs are displayed as stars, where the rays represent (1-alpha) confidence intervals.

Argument that helps to control the appearance (the width) of the stars that represent the confidence intervals of both parameters (location and response style) corresponding to one covariate. |
