WebDec 25, 2005 · Time series derived from simpler systems are single scale based and thus can be quantified by using traditional measures of entropy. However, times series derived from physical and biological systems are complex and show structures on multiple spatio-temporal scales. Traditional approaches of entropy based complexity measures fail to …
