mlogit (version 0.2-3)

plot.mlogit: Plot of the distribution of estimated random parameters

Description

Methods for rpar and mlogit objects which provide a plot of the distribution of one or all of the estimated random parameters

Usage

## S3 method for class 'mlogit':
plot(x, par = NULL, norm = NULL,
                      type = c("density", "probability"), ...)
## S3 method for class 'rpar':
plot(x, norm = NULL, type = c("density","probability"), ...)

Arguments

x

a mlogit or a rpar object,

type

the function to be plotted, whether the density or the probability density function,

par

a subset of the random parameters ; if NULL, all the parameters are selected,

norm

the coefficient's name for the mlogit method or the coefficient's value for the rpar method used for normalization,

...

further arguments, passed to plot.rpar for the mlogit method and to plot for the rpar method.

Details

For the rpar method, one plot is drawn. For the mlogit method, one plot for each selected random parameter is drawn.
