bct.v: Applying the Box-Cox Transformation to a numeric vector.

In bcmixed: Mixed Effect Model with the Box-Cox Transformation

Description

bct.v returns the Box-Cox transformed numeric vector (Box and Cox, 1964).

Usage

bct.v(y, lmdint = c(-3, 3))

Arguments

y	a positive real number vector.
lmdint	a vector containing the end-points of the interval to be searched for a transformation parameter. Default is c(-3, 3).

Value

bct.v returns the Box-Cox transformed numeric vector and estimated transformation parameter.

transformed

The Box-Cox transformed numeric vector.

lambda

a numeric value of the estimate of the transformation parameter.
