Detailed Description
Score given by the difference by the group means.Member Function Documentation
| double theplu::yat::statistics::Score::score | ( | const classifier::Target & | target, | |
| const classifier::DataLookup1D & | value, | |||
| const classifier::DataLookup1D & | weight | |||
| ) | const [inherited] |
Function calculating the weighted version of score. In absolute mode, also the score using negated class labels is calculated, and the largest of the two scores are calculated. Absolute mode should be used when two-tailed test is wanted.
value and weight are copied to utility::vector and the corresponding operator is called. If speed is important this operator should be implemented in inherited class to avoid copying.
| virtual double theplu::yat::statistics::Score::score | ( | const classifier::Target & | target, | |
| const classifier::DataLookup1D & | value | |||
| ) | const [virtual, inherited] |
Function calculating the score. In absolute mode, also the score using negated class labels is calculated, and the largest of the two scores are calculated.
value is copied to a utility::vector and that operator is called. If speed is important this operator should be implemented in inherited class to avoid copying.
- Returns:

Implements theplu::yat::statistics::Score.
Member Data Documentation
bool theplu::yat::statistics::Score::absolute_ [protected, inherited] |
true if method is absolute, which means if score is below expected value (by chance) E, score returns E-score+E instead.
