- Title
Rest Quantified by a Fractal Dimension of Movement Events: A Biomedical Application of Intermittency Estimation.
- Authors
Bickel, David R.
- Abstract
The intermittency of a time-series, i.e. the extent to which it departs from slowly-varying, unifractal dynamics, can often be quantified by simple scale-free statistics. For fractal point processes, singular measures, and certain other models that describe physical and biological phenomena, the correlation co-dimension, C[sub 2], quantifies intermittency. C[sub 2] of human activity during the night quantifies restfulness in that it is negatively correlated with the average activity level. However, C[sub 2] of activity appears to be more sensitive to the use of steroids than the average activity level.
