I am pleased to announce that vtreat version 0.6.0 is now available to R users on CRAN.


vtreat is an excellent way to prepare data for machine learning, statistical inference, and predictive analytic projects. If you are an R user we strongly suggest you incorporate vtreat into your projects.

vtreat handles, in a statistically sound fashion:

In our (biased) opinion opinion vtreat has the best methodology and documentation for these important data cleaning and preparation steps. vtreat‘s current public open-source implementation is for in-memory R analysis (we are considering ports and certifying ports of the package some time in the future, possibly for: data.table, Spark, Python/Pandas, and SQL).

vtreat brings a lot of power, sophistication, and convenience to your analyses, without a lot of trouble.

A new feature of vtreat version 0.6.0 is called “custom coders.” Win-Vector LLC‘s Dr. Nina Zumel is going to start a short article series to show how this new interface can be used to extend vtreat methodology to include the very powerful method of partial pooled inference (a term she will spend some time clearly defining and explaining). Time permitting, we may continue with articles on other applications of custom coding including: ordinal/faithful coders, monotone coders, unimodal coders, and set-valued coders.

Please help us share and promote this article series, which should start in a couple of days. This should be a fun chance to share very powerful methods with your colleagues.
