class EWStatsTransformer extends Transformer with Params with DefaultParamsWritable

Created by eugeny.malyutin on 06.05.16. implementation of continuously EWMA/EWMVar(Exponential-Weighted)/Sig(~=z-score) updater as mllib Transformer Term, newFreq, oldEWMA,oldEWMVar -> EWStruct(newEWMA, newEWMVar, Sig)

Formulas comes from here: T. Finch. Incremental calculation of weighted mean and variance. Technical report, University of Cambridge, 2009.
