Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The dependence of a couple of generalized FGM Copulas are studied in this paper. We solved their linear correlation coefficients r and concordance measures Kendall´s τ and Spearman´s ρ. Taking the relief factors of debris flow of drainage height difference and cutting degree for the examples, the concordance measures τ and ρ 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 τ and ρ to set out the specific Copulas, which can be better fitting to the dependence structure of drainage height difference and cutting degree.
