Classes Methods |
The Classes type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | Decide(Double) |
Hyperplane decision function. Return true if distance
is higher than zero, and false otherwise.
|
| Decide(Double) |
Hyperplane decision function. Return true if distance
is higher than zero, and false otherwise.
|

| Expand(Int32, Int32, Int32) |
Extends a grouped data into a full observation matrix.
|
| Expand(Int32, Int32, Int32, Int32) |

|
| GetRatio(Int32, Int32) |
Calculates the prevalence of a class for each variable.

Gets the percentage of positive samples in a set of class labels.
|
| GetRatio(Int32, Int32, Int32) |
Calculates the prevalence of a class.
|
| IsBinary |
Determines whether the class labels contains only (-1 and +1) or (0 and +1).
|
| IsMinusOnePlusOne |
Determines whether the class labels contains only -1 and +1.
|
| IsMulticlass |
Determines whether the class labels contains one true value per sample.
|
| IsMultilabel |
Determines whether the class labels contains one true value per sample.
|
| IsZeroOne |
Determines whether the class labels contains only zero and ones.
|
 | Random(Int32, Double) |
Returns a random group assignment for a sample
into two mutually exclusive groups.
|
| Random(Int32, Double) |
Returns a random group assignment for a sample.
|
| Random(Int32, Int32) |
Returns a random group assignment for a sample.
|
| Random(Int32, Double) |
Returns a random group assignment for a sample, making
sure different class labels are distributed evenly among
the groups.
|
| Random(Int32, Int32) |

sure different class labels are distributed evenly among
the groups.
|
| Random(Int32, Int32, Int32) |

sure different class labels are distributed evenly among
the groups.
|
| SeparateT(T, Int32) |
Divides values into groups given a vector
containing the group labels for every value.
|
| SeparateT(T, Int32, Int32) |
Divides values into groups given a vector
containing the group labels for every value.
|
| Summarize |
Groups the occurrences contained in data matrix of binary (dichotomous) data.
This operation can be reversed using the Expand(Int32, Int32, Int32, Int32) method.
