getLambda: Get Optimal Lambda value

In normalr: Normalisation of Multiple Variables in Large-Scale Datasets

Description

Computes optimal lambda value using boxcox function from the provided data.

Usage

getLambda(dat, lambda = seq(-10, 10, 1/100), parallel = TRUE)

Arguments

dat	a data frame containing the variables of numeric or integer vectors.
lambda	a vector of values of lambda <e2><80><93> default (-10, 10) in steps of 0.01.
parallel	perform the computation in parallel, default setting is TRUE.

Value

a numeric vector
