public class FixedRateMerit
extends EvenlySpacedMerit

A flavour of the EvenlySpacedMerit. A fixed rate merit always schedules the next observation to the first (succesful) observation. This means that, in the long run, the frequency of the observations will be equal to the reciprocal of the stated period.
