rpar objects contain all the relevant information about
the distribution of random parameters. These functions enables to
obtain easily descriptive statistics, density, probability and
quantiles of the distribution.

drpar(x, par = 1, y = NULL, norm = NULL, ...)a mlogit or a rpar object,
the variable used for normalization if any : for the
mlogit method, this should be the name of the parameter, for
the rpar method the absolute value of the parameter,
the required parameter(s) for the mlogit methods (either
the name or the position of the parameter(s). If NULL, all
the random parameters are used.
values for which the function has to be evaluated,
further arguments.
a numeric vector for qrpar, drpar and prpar, a
numeric vector for mean, stdev and med and a
numeric matrix for rg.
mean, med, stdev and rg compute
respectively the mean, the median, the standard deviation and the
range of the random parameter. qrpar, prpar,
drpar return functions that compute the quantiles, the
probability and the density of the random parameters (note that
sd and range are not generic function in R and
that median is, but without ...).
mlogit for the estimation of random parameters logit models
and rpar for the description of rpar objects.
