Hello, I have been programming some visual methods for transforming data using the BoxCox family of transformations (logs, squares,..) and the Folded Power (arcsin, logistic,...). I would like to get a good numerical example (with the history of the data, please) for aplying the second set of transformations, i.e., for transforming proportions. Is anybody aware of any very good dataset for using these transformations? Thanks in advance, Pedro ========================================================== Dr. Pedro M. Valero-Mora.
