rpar: random parameter objects

In mlogit: Multinomial Logit Models

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 '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

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.
