The flip-flop effect in entropy estimation

The paper investigates the flip-flop effect in entropy estimates: approximate, sample and fuzzy. It was tested in signals recorded from male rats, Wistar ones and borderline hypertensive ones, exposed to various types of stress - shaker and restraint. The occurrence of flip-flop effect cannot be predicted, so the parameters of entropy estimates must be chosen in a way that this unwanted occurrence should be avoided.
