(1) Tdelay=argmaxτ(R(τ)),(2) where S1 and S2 are the two time series to be computed, τ is the time lag, R(τ) is the correlation coefficient calculated between S1 and S2 when the time lag is τ, argmaxτ refers to the argument (in this case, the time lag τ) at which the values of the function R(τ) are maximized.
