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.
