random parameter objects
Description
rpar objects contain the relevant information about estimated
random parameters. The homonymous function extract on rpar object
from a mlogit object.
Usage
rpar(x, par = NULL, norm = NULL, ...)
## S3 method for class 'rpar'
print(
x,
digits = max(3, getOption("digits") - 2),
width = getOption("width"),
...
)
## S3 method for class 'rpar'
summary(object, ...)
Arguments
x, object |
a |
par |
the name or the index of the parameters to be extracted
; if |
norm |
the coefficient used for normalization if any, |
... |
further arguments. |
digits |
the number of digits |
width |
the width of the printed output |
Details
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.
Value
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.
