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, ...)

Arguments

x

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.

Value

• a rpar object, which contain :
• 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.
