rpar {mlogit} | R Documentation |
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.
