Quantlet: TailCoeffEstimation
Description: estimates the upper or lower tail-dependence coefficient via a bivariate empirical copula.

Usage: TDC = TailCoeffEstimation(data, threshold, upper)
Input:
data n x 2 matrix, data matrix
threshold scalar, number of exceedances
upper string, either "upper" or "lower", specifies whether the upper or lower tail-dependence coefficient should be estimated
Output:
TDC scalar, upper or lower tail-dependence coefficient

Note:

Example:
library("VaR")
randomize(1)
data=VaRsimcopula(1000,1,1,2,4)
TDC=TailCoeffEstimation(data,82,"upper")
TDC

Result:
Plots graph of upper-tail dependence coefficient.
