Method Detail

compute

public Map<Integer,Double> compute(Collection<? extends Number> dataset)

Computes the quantile values of the given dataset.

Parameters:

dataset - the dataset to do the calculation on, which must be non-empty, which will be cast to doubles (with any associated lost of precision), and which will not be mutated by this call (it is copied instead)

Returns:

an unmodifiable map of results: the keys will be the specified quantile indexes, and the values the corresponding quantile values

compute

public Map<Integer,Double> compute(double... dataset)

Computes the quantile values of the given dataset.

Parameters:

dataset - the dataset to do the calculation on, which must be non-empty, which will not be mutated by this call (it is copied instead)

Returns:

an unmodifiable map of results: the keys will be the specified quantile indexes, and the values the corresponding quantile values

compute

public Map<Integer,Double> compute(long... dataset)

Computes the quantile values of the given dataset.

Parameters:

dataset - the dataset to do the calculation on, which must be non-empty, which will be cast to doubles (with any associated lost of precision), and which will not be mutated by this call (it is copied instead)

Returns:

an unmodifiable map of results: the keys will be the specified quantile indexes, and the values the corresponding quantile values

compute

public Map<Integer,Double> compute(int... dataset)

Computes the quantile values of the given dataset.

Parameters:

dataset - the dataset to do the calculation on, which must be non-empty, which will be cast to doubles, and which will not be mutated by this call (it is copied instead)

Returns:

an unmodifiable map of results: the keys will be the specified quantile indexes, and the values the corresponding quantile values

computeInPlace

public Map<Integer,Double> computeInPlace(double... dataset)

Computes the quantile values of the given dataset, performing the computation in-place.

Parameters:

dataset - the dataset to do the calculation on, which must be non-empty, and which will be arbitrarily reordered by this method call

Returns:

an unmodifiable map of results: the keys will be the specified quantile indexes, and the values the corresponding quantile values
