Introduction: The object of this document is to present a brief and concise introduction to Hurst ReScaling. More detail is presented in a paper by Outcalt et.al. (1997), which is posted on the WUWT
Website ( http://wattsupwiththat.wpcomstaging.com/wp-content/uploads/2012/07/sio_hurstrescale-1.pdf ). A extensive reference list in this paper can be consulted so references are omitted here.
