R: Class "FParameter"

FParameter-class {distr} | R Documentation

## Class "FParameter"

### Description

The parameter of a F distribution, used by Fd-class

### Objects from the Class

Objects can be created by calls of the form `new("FParameter", df1, df2, ncp)`. Usually an object of this class is not needed on its own, it is generated automatically when an object of the class Fd is instantiated.

### Slots

`df1`

  Object of class `"numeric"`: the degrees of freedom of the nominator of an F distribution

`df2`

  Object of class `"numeric"`: the degrees of freedom of the denominator of an F distribution

`ncp`

  Object of class `"numeric"`: the noncentrality parameter of an F distribution

`name`

  Object of class `"character"`: a name / comment for the parameters

### Extends

Class `"Parameter"`, directly.

### Methods

initialize

  `signature(.Object = "FParameter")`: initialize method

df1

  `signature(object = "FParameter")`: returns the slot df1 of the parameter of the distribution

df1<-

  `signature(object = "FParameter")`: modifies the slot df1 of the parameter of the distribution

df2

  `signature(object = "FParameter")`: returns the slot df2 of the parameter of the distribution

df2<-

  `signature(object = "FParameter")`: modifies the slot df2 of the parameter of the distribution

ncp

  `signature(object = "FParameter")`: returns the slot `ncp` of the parameter of the distribution

ncp<-

  `signature(object = "FParameter")`: modifies the slot `ncp` of the parameter of the distribution

### Examples

    W <- new("FParameter", df1 = 1, df2 = 1, ncp = 0)
    df2(W) # df2 of this distribution is 1.
    df2(W) <- 2 # df2 of this distribution is now 2.
