Equal width binning divides data into intervals with equal width but the data volume of each bin varies. In DolphinDB, you can use the
bucketfunction.Equal frequency binning divides data evenly into intervals with equal data volume. In DolphinDB, you can use the
rankfunction to specify the groupNum or use thebarfunction to specify the interval.
