Assessment of the state of the computer system based on the hurst exponent [PDF]

open access: yes, 2017
The method of identifying abnormal behavior of computer systems based on the Hurst exponent is examined in this report. Results of the research suggest the possibility of using the Hurst exponent for identifying the anomalous behavior of computer systems

Martingales, the efficient market hypothesis, and spurious stylized facts [PDF]

open access: yes, 2007
The condition for stationary increments, not scaling, detemines long time pair autocorrelations. An incorrect assumption of stationary increments generates spurious stylized facts, fat tails and a Hurst exponent Hs=1/2, when the increments are ...
