R: Class "BetaParameter"

BetaParameter-class {distr} | R Documentation

## Class "BetaParameter"

### Description

The parameter of a beta distribution, used by `Beta-class`

### Objects from the Class

Objects can be created by calls of the form `new("BetaParameter", shape1, shape2, ncp)`. Usually an object of this class is not needed on its own, it is generated automatically when an object of the class Beta is instantiated.

### Slots

`shape1`

  Object of class `"numeric"`: the shape1 of a beta distribution

`shape2`

  Object of class `"numeric"`: the shape2 of a beta distribution

`ncp`

  Object of class `"numeric"`: the noncentrality parameter of a beta distribution

`name`

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

### Extends

Class `"Parameter"`, directly.

### Methods

initialize

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

shape1

  `signature(object = "BetaParameter")`: returns the slot shape1 of the parameter of the distribution

shape1<-

  `signature(object = "BetaParameter")`: modifies the slot shape1 of the parameter of the distribution

shape2

  `signature(object = "BetaParameter")`: returns the slot shape2 of the parameter of the distribution

shape2<-

  `signature(object = "BetaParameter")`: modifies the slot shape2 of the parameter of the distribution

ncp

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

ncp<-

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

    W <- new("BetaParameter", shape1 = 1, shape2 = 1, ncp = 0)
    shape2(W) # shape2 of this distribution is 1.
    shape2(W) <- 2 # shape2 of this distribution is now 2.
