Dependence Structure of Two Relief Factors of Debris Flow
The dependence of a couple of generalized FGM Copulas are studied in this paper. We solved their linear correlation coefficients r and concordance measures Kendalls T and Spearmans p. Taking the relief factors of debris flow of drainage height difference and cutting degree for the examples, the concordance measures T and p of the two relief factors were calculated to show that the relationship of them can be better prepared to that of the datas. Furthermore, we discussed the value ranges of X and p to set out the specific Copulas, which can be better fitting to the dependence structure of drainage height difference and cutting degree.
