VectorStatCollector

class VectorStatCollector extends Transformer with HasInputCol with HasGroupByColumns with DefaultParamsWritable

Utility used to collect detailed stat for vectors grouped by a certain keys. In addition to common stuff (mean, variance, min/max, norms) calculates percentiles as configured. Resulting dataframe contains only columns from the key and stat columns.
