rpar objects contain the relevant information about
estimated random parameters. The homonymous function extract on
rpar object from a mlogit object.
rpar(x, par = NULL, norm = NULL, ...)a mlogit object,
the name or the index of the parameters to be extracted ;
if NULL, all the parameters are selected,
the coefficient used for normalization if any,
further arguments.
a rpar object, which contain :
the name of the distribution,
the first parameter of the distribution,
the second parameter of the distribution,
the name of the parameter,
mlogit objects contain an element called rpar which contain a list
of rpar objects, one for each estimated random parameter. The
print method prints the name of the distribution and the
parameter, the summary behave like the one for numeric vectors.
mlogit for the estimation of a random parameters logit model.
