Enum Constant Summary

Enum Constants

Enum Constant and Description
APPROXIMATELY_MEDIAN_UNBIASED default: the resulting quantile estimates are approximately median-unbiased regardless of the distribution of the sample
APPROXIMATELY_UNBIASED_IF_DATA_IS_NORMAL the resulting quantile estimates are approximately unbiased for the expected order statistics if the sample is normally distributed
INVERSE_OF_EMPIRICAL_CDF the inverse of empirical distribution function
INVERSE_OF_EMPIRICAL_CDF_WITH_AVERAGING_AT_DISCONTINUITIES the inverse of empirical distribution function with averaging at discontinuities
LINEAR_INTERPOLATION_OF_EMPIRICAL_CDF the linear interpolation of the empirical cdf
MIDWAY_THROUGH_STEPS_OF_EMPIRICAL_CDF a piecewise linear function where the knots are the values midway through the steps of the empirical cdf
MINITAB_SPSS the definition in Minitab and SPSS
NEAREST_EVEN_ORDER_STATISTICS the nearest even order statistic as in SAS
S the definition in S

Method Detail

values

public static Quantile.QuantileType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Quantile.QuantileType c : Quantile.QuantileType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Quantile.QuantileType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
