Figure 13From: Communication patterns in a psychotherapy following traumatic brain injury: A quantitative case study based on symbolic dynamics Lempel-Ziv complexity and normalized complexity as a function of data set size. Symbol sequences were generated from the previously defined model systems using a binary partition about the median. The upper panel shows Lempel-Ziv complexity. The lower panel shows the corresponding normalized complexity where values of Lempel-Ziv complexity are normalized against random, equi-probable surrogates. In these calculations 499 surrogates were used to compute CN (modified from Rapp, 2007).Back to article page
