Methods for rpar and mlogit objects which provide a plot of the
distribution of one or all of the estimated random parameters
# S3 method for mlogit
plot(x, par = NULL, norm = NULL, type = c("density", "probability"), ...)# S3 method for rpar
plot(x, norm = NULL, type = c("density", "probability"), ...)
a mlogit or a rpar object,
a subset of the random parameters ; if NULL, all the
parameters are selected,
the coefficient's name for the mlogit method or the
coefficient's value for the rpar method used for
normalization,
the function to be plotted, whether the density or the probability density function,
further arguments, passed to plot.rpar for the
mlogit method and to plot for the rpar method.
Yves Croissant
For the rpar method, one plot is drawn. For the mlogit method,
one plot for each selected random parameter is drawn.
mlogit() the estimation of random parameters logit
models and rpar() for the description of rpar objects and
distribution for functions which return informations about
the distribution of random parameters.
