Class IterableVar<V>

java.lang.Object

org.tensorics.core.scalar.lang.ScalarSupport<V>

org.tensorics.core.iterable.operations.IterableVar<V>

Type Parameters:

V - the type of the scalars (elements of the field on which the variance will be based)

All Implemented Interfaces:

java.util.function.Function<java.lang.Iterable<V>,V>, BasicOperationSupport<V>, Conversion<java.lang.Iterable<V>,V>, IterableOperation<V>

public class IterableVar<V>
extends ScalarSupport<V>
implements IterableOperation<V>

An operation that takes and iterable of a certain type of values (for which a field has to be provided) and calculates the variance out of it.

For the definition of the variance, have a look at wikipedia.
