Class "TParameter"

Objects from the Class

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

Slots

df:
Object of class "numeric": the degrees of freedom of a T distribution
ncp:
Object of class "numeric": the noncentrality parameter of a T distribution
name:
Object of class "character": a name / comment for the parameters

Extends

Class "Parameter", directly.

Methods
