Interface Statistics

All Superinterfaces:

Range

public interface Statistics
extends Range

The statistics of a given set of numbers.

For the purpose of statistics calculation, NaNs should be skipped. That is, they should not appear as minimum, maximum, average or stdDev, and shouldn't even be included in the count. The number of elements (including NaNs) will be available from the number set itself.

The appropriate Statistics instance for an unknown set, or for a set of NaN values, is null.
