Joint Multifractal Analysis and Source Testing of River Level Records Based on Multifractal Detrended Cross-Correlation Analysis

Figure 4

Testing via pair of surrogate series . X-axis denotes the range of values. Triangles indicate of two preprocessed daily average river levels at adjacent sites. Circles indicate obtained via simultaneously half-shifting technique. The shadow area indicates acceptance region of at 5% significance level estimated from 1000 pairs of surrogate series for the null hypothesis : the joint multifractality is not due to the correlations within and between series.
