Are you aware of any R function that allows you to apply both univariate and multivariate BoxCox transformations to probability weighted data. Computes and optionally plots profile log-likelihoods for the parameter of the Box-Cox power family the Yeo-Johnson power family or for either of the parameters in a bcnPower family. It indicates both the value that maximizes the log-likelihood as well as a confidence interval for the λ λ value that maximizes the log-likelihood. You could use the Boxcox function of the MASS package to find out what transformation is needed.
