Enum Constant Detail

TWO_SIDED

public static final AlternativeHypothesis TWO_SIDED

Represents a two-sided test. H0: p=p0, H1: p ≠ p0

GREATER_THAN

public static final AlternativeHypothesis GREATER_THAN

Represents a right-sided test. H0: p ≤ p0, H1: p > p0.

LESS_THAN

public static final AlternativeHypothesis LESS_THAN

Represents a left-sided test. H0: p ≥ p0, H1: p < p0.

Method Detail

values

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

Returns:

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

valueOf

public static AlternativeHypothesis 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
