Utils: Data transformation (Box-Cox, 1964)

Description

Estimates the lambda value for data transformation

Usage

transf(response, f1, f2 = NA, f3 = NA, block = NA, line = NA, column = NA)

Arguments

response

Numerical vector containing the response of the experiment.

f1

Numeric or complex vector with factor 1 levels

f2

Numeric or complex vector with factor 2 levels

f3

Numeric or complex vector with factor 3 levels

block

Numerical or complex vector with blocks

line

Numerical or complex vector with lines

column

Numerical or complex vector with columns

Value

Returns the value of lambda and/or data transformation approximation, according to Box-Cox (1964)
