Method Detail

quantile

public static double quantile(@NotNull
                              F64Array $receiver,
                              double q,
                              @NotNull
                              org.apache.commons.math3.random.RandomGenerator randomGenerator)

Computes the q-th order statistic over this 1-D array.

The implementation follows that of Commons Math. See JavaDoc of org.apache.commons.math3.stat.descriptive.rank.Percentile for computational details.

The array is modified in-place. Do a F64Array.copy of the array to avoid mutation if necessary.

shuffle

public static void shuffle(@NotNull
                           F64Array $receiver,
                           @NotNull
                           org.apache.commons.math3.random.RandomGenerator randomGenerator)

Randomly permutes the elements of this 1-D array.
