Interface Sample.Derived

All Superinterfaces:

Sample

Enclosing interface:

Sample

public static interface Sample.Derived
extends Sample

Sample that does not exist as an actual observation but is derived from actual observations. E.g., mean. Most derived sample instances have a reference to an actual sample that is an exemplar for the derived sample. Because derived samples are typically computed from actual samples, the value is a double (rather than a long as with the actual samples).
