onesidedBias-class {distrMod}

onesided Bias Type

Description

Class of onesided bias types.

Objects from the Class

Objects can be created by calls of the form new("onesidedBias", ...). More frequently they are created via the generating function positiveBias or negativeBias.

Slots

name

Object of class "character".

sign

Object of class "numeric"; to be in {-1,1} — whether bias is to be positive or negative

Methods

sign

signature(object = "onesidedBias"): accessor function for slot sign.

sign<-

signature(object = "onesidedBias", value = "numeric"): replacement function for slot sign.

Extends

Class "BiasType", directly.

Examples

positiveBias()
## The function is currently defined as
function(){ new("onesidedBias", name = "positive Bias", sign = 1) }

negativeBias()
## The function is currently defined as
function(){ new("onesidedBias", name = "negative Bias", sign = -1) }

pB <- positiveBias()
sign(pB)
try(sign(pB) <- -2) ## error
sign(pB) <- -1
