mlogit (version 1.1-1)

rpar: 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 rpar
print(
  x,
  digits = max(3, getOption("digits") - 2),
  width = getOption("width"),
  ...
)
# S3 method for rpar
summary(object, ...)

Arguments

x, object

a mlogit object,

par

the name or the index of the parameters to be extracted ; if NULL, all the parameters are selected,

norm

the coefficient used for normalization if any,

...

further arguments.

digits

the number of digits

width

the width of the printed output

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.

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.
