We numerically test the method of non-sequential recursive pair substitutionsto estimate the entropy of an ergodic source. We compare its performance withother classical methods to estimate the entropy (empirical frequencies, returntimes, Lyapunov exponent). We considered as a benchmark for the methods severalsystems with different statistical properties: renewal processes, dynamicalsystems provided and not provided with a Markov partition, slow or fast decayof correlations. Most experiments are supported by rigorous mathematicalresults, which are explained in the paper.
