class CRRSamplerEstimator extends Estimator[CRRSamplerModel] with DefaultParamsWritable with CRRSamplerParams

Estimator is used to select the proper item sample rate to achive desired size of the resulting sample. Takes into consideration the source dataset size and the amount of valid for ranking lists (list with samples of different rank).
