Klimontovich's S-Theorem Algorithm Implementation and Data Preparation Tools
Functions in this package implement the procedure based on Klimontovich's S-theorem. This procedure compares relative degree of order between two data arrays. Klimontovich's S-theorem was originally proposed by Klimontovich (1987) as analytical modeling tool for open thermodynamic systems, and it sets the "renormalized entropy" as a criterion of relative degree of order for two probability density functions associated with two states of the thermodynamic system by equating the mean effective energies. Anishchenko (1994) extended the original concept and designed the algorithm for numerical comparison of two data samples. It has been used for many models such as heart rate variability time series by Wessel (1994) & Anishchenko (1995), variability of electroencephalograms of epilepsy patients by Kopizki (2002), relative degree of ordering in images by Herega (2010), self-organization of dissipative optical lattices by Bagci (2009) etc.
Two functions are directly related to Klimontovich's S-theorem algorithm. Function
crit.stheorem checks the method applicability for certain pair of sample distributions and function
cxds.stheorem estimates the renormalized entropy difference between two sample distributions after equating the mean energies. The package also contains data preparation tools (for cleaning, formatting, filtering etc.) which can also be used separately, e.g. for descriptive statistics and/or as helpful instruments for time-series analysis, signal and image processing.
It has been created with support of the Science Foundation Ireland under Grant No. 13/TIDA/B2688
