Instance Constructors

  1. new ZscoreTransformer(means: IndexedSeq[Double], standardDeviations: IndexedSeq[Double])

    means

    A sequence of Doubles, each of which is the mean value for the corresponding dimension.

    standardDeviations

    A sequence of Doubles, each of which is the standard deviation computed from the values for a given dimension.
