Interface QOM.CovarPop

All Superinterfaces:

AggregateFilterStep<BigDecimal>, AggregateFunction<BigDecimal>, Field<BigDecimal>, FieldOrConstraint, FieldOrRow, FieldOrRowOrSelect, GroupField, Named, OrderField<BigDecimal>, QueryPart, SelectField<BigDecimal>, SelectFieldOrAsterisk, Serializable, TableElement, Typed<BigDecimal>, WindowBeforeOverStep<BigDecimal>, WindowOverStep<BigDecimal>

Enclosing class:

QOM

public static interface QOM.CovarPop
extends AggregateFunction<BigDecimal>

The COVAR POP function.

Calculate the population covariance. This standard SQL function may be supported natively, or emulated using DSL.sum(Field) and DSL.count(Field). If an emulation is applied, beware of the risk of "Catastrophic cancellation" in case the calculations are performed using floating point arithmetic.
