List of falsePositiveRate() Examples

Examples of falsePositiveRate()

weka.classifiers.Evaluation.falsePositiveRate()
Calculate the false positive rate with respect to a particular class. This is defined as
```
 incorrectly classified negatives -------------------------------- total negatives 
```
@param classIndex the index of the class to consider as "positive" @return the false positive rate

Examples of weka.classifiers.Evaluation.falsePositiveRate()

    result[current++] = new Double(eval.KBRelativeInformation());
    
    // IR stats
    result[current++] = new Double(eval.truePositiveRate(m_IRclass));
    result[current++] = new Double(eval.numTruePositives(m_IRclass));
    result[current++] = new Double(eval.falsePositiveRate(m_IRclass));
    result[current++] = new Double(eval.numFalsePositives(m_IRclass));
    result[current++] = new Double(eval.trueNegativeRate(m_IRclass));
    result[current++] = new Double(eval.numTrueNegatives(m_IRclass));
    result[current++] = new Double(eval.falseNegativeRate(m_IRclass));
