- Add "post-transformation" to printout of different transforms' means and sds to clarify output
- Added other transformations commonly used to normalize a vector
- exponential, log, square root, arcsinh
- Lambert WxF is no longer done by default by bestNormalize since it is unstable on certain OS (Linux, Solaris), and does not abide by the CRAN policy.
- Clarified that the transformations are standardized by default, and providing option to not standardize in transformations
- Updated tests to run a bit faster and to use proper S3 classes
- Added references for original papers (Van der Waerden, Bartlett) that cite the basis for the orderNorm transformation, as well as discussion in Beasley (2009)
- Edited description to clarify that this procedure is a new adaptation of an older technique rather than a new technique in itself
-
Added feature to estimate out-of-sample normality statistics in bestNormalize instead of in-sample ones via repeated cross-validation
- Note: set
out_of_sample = FALSEto maintain backward-compatibility with prior versions and setallow_orderNorm = FALSEas well so that it isn't automatically selected
- Note: set
-
Improved extrapolation of the ORQ (orderNorm) method
- Instead of linear extrapolation, it uses binomial (logit-link) model on ranks
- No more issues with Cauchy transformation
-
Added plotting feature for transformation objects
-
Cleared up some documentation
- Changed the name of the orderNorm technique to "Ordered Quantile normalization".
- Made description more clear in response to comments from CRAN
