We also give the asymptotic distribution of an affine transformation of the permutation entropy under the null hypothesis of independence. An application to several daily financial time series illustrates our approach. %K Economía Aplicada %K Entropía %K Independencia %K I.i.d %K Invariación %K Serie temporal no lineal %K Dinámica simbólica %K Camino aleatorio (Random Walk) %K Entropy %K Independence %K Invariance %K Nonlinear time serie %K Symbolic dynamic %~ GOEDOC, SUB GOETTINGEN
