“…It is clear that this approach does not address in any way the issues of causality, and hence of remediation, only those of prediction and law enforcement. The pattern-recognition approach was thus extended, based on the above reasoning, to the start of economic recessions (Keilis-Borok et al, 2000), to episodes of sharp increase in the unemployment rate, called fast acceleration of unemployment (FAU; Keilis-Borok et al, 2005), and to homicide surges in megacities (Keilis-Borok et al, 2005). Based on these applications to complex economic and social systems, we try to formulate here a universal algorithm that is applied to monthly series of several relevant indices of system activity, including the appropriate definition of parameter values for the prediction of the extreme events of interest in the given system.…”
