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 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) 
Returns a random group assignment for a sample, making
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.
