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 called Range entropy or RangeEn. RangeEn measures represent a better robustness to nonstationary changes in signals and a more linear link to the Hurst exponent compared to ApEn and SampEn. They are always bounded in the tolerance r-plane are constrained between 0 (maximum entropy) and 1 (minimum entropy) .
