Detailed Description

Abstract base class for Hurst exponent calculation.

This base class defines the local hurstInfo class which is a container for the linear regression data calculated either through the R/S or wavelet spectrum points. The base class also provides some utility functions: log2 (log, base 2) and print_regression_points, which was used for debugging and printing data for plot creation (e.g., the plots on the associated web pages).

The base class also defines the calc_hurst_est interface (e.g., virtual function).
