Finding Optimal Lambda for Box-Cox Transform in R

Question

I am trying to transform data in a vector in R.

This is not for linear regression so I don\'t have a predictor and response relationship. I am simply using a model that

Answer 1

For applying box cox transformation on vector, use forecast package in r:

library(forecast)
# to find optimal lambda
lambda = BoxCox.lambda( vector )
# now to transform vector
trans.vector = BoxCox( vector, lambda)
