Enclosing class:

ChiSquare4Independence

public static enum ChiSquare4Independence.Type
extends java.lang.Enum<ChiSquare4Independence.Type>

the distribution used for the test

Enum Constant Summary

ASYMPTOTIC_CHI_SQUARE
default: the asymptotic distribution of the Fisher's exact test distribution; appropriate for a large and well balanced sample

EXACT
the distribution for Fisher's exact test; appropriate when the sample size is small and contingency table unbalanced

Method Summary

static ChiSquare4Independence.Type	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static ChiSquare4Independence.Type[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

EXACT

public static final ChiSquare4Independence.Type EXACT

the distribution for Fisher's exact test; appropriate when the sample size is small and contingency table unbalanced

ASYMPTOTIC_CHI_SQUARE

public static final ChiSquare4Independence.Type ASYMPTOTIC_CHI_SQUARE

default: the asymptotic distribution of the Fisher's exact test distribution; appropriate for a large and well balanced sample

Method Detail

values

public static ChiSquare4Independence.Type[] 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 (ChiSquare4Independence.Type c : ChiSquare4Independence.Type.values())
    System.out.println(c);

Returns:

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

valueOf

public static ChiSquare4Independence.Type valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
