SCT basics. Scheme for calculating the bivariate word distribution which underlies SCT. At first, a symbolic representation of two time series is derived by means of encoding as depicted in Equation 3 (휗=1). From the symbolic representation, words of length l=3 and respective word sequences are derived which establish a joint bivariate probability distribution. In this example, the delay between word pairs is τ=0.
