dncp: Density of noncentrality parameters

Description

These functions return the density function of noncentrality parameters, from ncpest objects

Usage

dncp(obj, ...)
## S3 method for class 'parncpt':
dncp(obj, fold=FALSE, ...)
## S3 method for class 'nparncpt':
dncp(obj, fold=FALSE, ...)
## S3 method for class 'sparncpt':
dncp(obj, fold=FALSE, ...)
## S3 method for class 'nparncpp':
dncp(obj, reflect=TRUE, ...)

Arguments

obj

an object of class ncpest, from which noncentrality parameter density to be extracted

fold

Logical: if TRUE, then the density of noncentrality paramters is folded about zero to give the density of absolute noncentrality parameters.

reflect

Logical: if TRUE, then the density of absolute noncentrality parameters is reflected about zero.

...

Further arguments.

Value

• A function of one argument
