Enclosing class:

Quantiles

public static final class Quantiles.ScaleAndIndex
extends Object

Describes the point in a fluent API chain where the scale and a single quantile index (i.e. the q and the k in the kth q-quantile) have been specified.

Method Detail

compute

public double compute(Collection<? extends Number> dataset)

Computes the quantile value 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:

the quantile value

compute

public double compute(double... dataset)

Computes the quantile value 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:

the quantile value

compute

public double compute(long... dataset)

Computes the quantile value 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:

the quantile value

compute

public double compute(int... dataset)

Computes the quantile value 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:

the quantile value

computeInPlace

public double computeInPlace(double... dataset)

Computes the quantile value 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
