                                         EvaluationResultCollection evalResultCollection)

Does print an evaluation result collection to an output stream.

Parameters:

context - the context

os - the output stream

evalResultCollection - the evaluation result collection to print

createLine

private static final String createLine(int len)

Does create a string representation of a line with the given length.

Parameters:

len - the line length in characters

Returns:

the line string

print

Does print the evaluation result to an output stream.

Parameters:

context - the context

os - the output stream

evalResult - the evaluation result to print

validationStrategy - the validation strategy

mapCid2Name - the mapping of class identifiers to names

getPerClassStatisticValueString

public static final String getPerClassStatisticValueString(Context context,
                                                           double[] measureValues,
                                                           String classLabel)

Does create a string representation of the per class statistic values as column entries with the class label in the end. All values but the class label will be printed right justified in the column. The width of each column is determined by its header.

Parameters:

context - the context

measureValues - the measure values

classLabel - the class label

Returns:

a string representation of the column headers

getPerClassStatisticHeaderString

public static final String getPerClassStatisticHeaderString(Context context,
                                                            boolean addClassColumn)

Does create a string representation of the per class statistic column headers.

Parameters:

context - the context

addClassColumn - if true a column for the class label is added in the end

Returns:

a string representation of the column headers
