Methodology of correlation coefficient calculation for non-stationary time series

D.S. Kirillov1, L.V Klochkova2, J.H. Orlov3, V.F. Tishkin4

AnnotationIn this paper we construct a method of determination of correlation coefficient for two non-stationary time series. In comparison with stationary case we need to determine the so-called optimal set length and confidence interval as empirical statistics.
Keywordsnon-stationary correlation coefficient, optimal set length, optimal confidence level.
