Instance Constructors

  1. new PoissonSampler(fraction: Double)(implicit arg0: ClassTag[T])

  2. new PoissonSampler(fraction: Double, useGapSamplingIfPossible: Boolean)(implicit arg0: ClassTag[T])

    fraction

    the sampling fraction (with replacement)

    useGapSamplingIfPossible

    if true, use gap sampling when sampling ratio is low.
