Before revision:  Our results suggest that, unlike ApEn and SampEn , RangeEnmeasures are robust to stationary and nonstationary signal amplitude variations and that their trajectories in the tolerance r-plane are constrained between 0 (maximum entropy) and 1 (minimum entropy)  .
After revision:  Our results suggest that, unlike ApEn and SampEn , RangeEnmeasures are robust to stationary and nonstationary signal amplitude variations and that their trajectories in the tolerance r-plane are constrained between 0 (maximum entropy) and 1 (minimum entropy) and need no signal amplitude correction .
