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, ...)# S3 method for rpar
print(
x,
digits = max(3, getOption("digits") - 2),
width = getOption("width"),
...
)
# S3 method for rpar
summary(object, ...)
a rpar object, which contains:
dist: the name of the distribution,
mean: the first parameter of the distribution,
sigma: the second parameter of the distribution,
name: the name of the parameter.
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.
the number of digits
the width of the printed output
Yves Croissant
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.
