public interface Statistics

Basic type for statistical information of numeric types. The methods never return null, even if no connection was ever made. One must always look at the alarm severity to be able to correctly interpret the value.

This type can be used regardless of the method used to calculate the average (instances: Σx_i/N, time: Σx_iΔt_i/Δt, time with linear interpolation, exponential backoff, ...).

No integer statistics, since averages are not integer in general.
