Enum Constant Detail

WEIGHTED_AVERAGE

public static final CrossValidationCombineMethod WEIGHTED_AVERAGE

Calculates the average of the numeric test results weighted by the number of records in each test partitioning. This would be appropriate when combining lift scores.

UNWEIGHTED_SUM

public static final CrossValidationCombineMethod UNWEIGHTED_SUM

Simply sums the numeric test results. This assumes that the weight has already been incorporated. This would be appropriate when combining log-likelihoods, which for each test partitioning are the sum of the log-likelihoods for each test case.

R_SQUARED

public static final CrossValidationCombineMethod R_SQUARED

Combines R-squared statistics calculated on different partitions of data.

Method Detail

values

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

Returns:

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

valueOf

public static CrossValidationCombineMethod 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
