distribution {mlogit} | R Documentation |
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.

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 ...
).
a numeric vector for qrpar
, drpar
and prpar
, a
numeric vector for mean
, stdev
and med
and a
numeric matrix for rg
.
