Detailed Description
Calculate the hypergeometric p-value of overlap between two boolean vectors (centering and weights ignored).
Returns the hypergeometric p-value of overlap given two boolean vectors, counting the total number of nonzero entries, the number of nonzero entries in each vector, and the number of positions in which both vectors are nonzero.

| IMeasure* Sleipnir::CMeasureHypergeometric::Clone | ( | ) | const [inline, virtual] |
Create a copy of the current measure object.
- Returns:
- Copy of the current measure object.
- Remarks:
- Caller is, of course, responsible for destroying the created object.
Implements Sleipnir::IMeasure.
| const char* Sleipnir::CMeasureHypergeometric::GetName | ( | ) | const [inline, virtual] |
Return the human-readable unique identifier of the measure type.
- Returns:
- The string identifier of the measure type.
Implements Sleipnir::IMeasure.
| bool Sleipnir::CMeasureHypergeometric::IsRank | ( | ) | const [inline, virtual] |
Return true if the measure requires rank-based integer inputs.
- Returns:
- True if the measure requires rank-based input vectors.
- Remarks:
- The input vectors for rank measures should contain only floating point values with no fractional part; behavior is undefined if they don't.

Calculate the measure between two given vectors with optional element weights.
- Parameters:
-
adX First array of values. iN Length of first array. adY Second array of values. iM Length of second array. eMap Way in which returned value should be centered (implementation-specific). adWX If non-null, weights of elements in the first array. adWY If non-null, weights of elements in the second array.
- Returns:
- Measure calculated between the two input vectors and, optionally, weights.
- Remarks:
- Pretty much every implementation will puke if given bad input; bounds checking etc. is minimal.
