Confidence intervals for the estimated parameter of a bivariate parametric copula using MMD estimation
BiCopConfIntMMD( x1, x2, family, nResampling = 100, subsamplingSize = length(x1), corrSubSampling = TRUE, level = 0.95, ... )
x1 |
vector of observations of the first coordinate. |
x2 |
vector of observations of the second coordinate. |
family |
parametric family of copulas. Supported families are:
|
nResampling |
number of resampling times. |
subsamplingSize |
size of the subsample.
By default it is |
corrSubSampling |
this parameter is only used for subsampling-based confidence intervals.
If |
level |
the nominal confidence level. |
... |
other parameters to be given to |
a list with the confidence intervals CI.Tau for Kendall's tau and CI.Par for the corresponding parameter.
