Bernoulli amputation
Marius Hofert, James Jackson, Niels Hagenbuch
A novel, stochastic approach to amputation, the process of introducing missing values to a complete dataset, is presented. It allows one to construct a wide variety of missingness…

Measuring multivariate maximal tail dependence
Takaaki Koike, Marius Hofert, Haruki Tsunekawa
The classical tail dependence coefficient (TDC) may fail to capture non-exchangeable features of bivariate tail dependence since it evaluates the underlying copula only along the d…

Tail copula representation of path-based maximal tail dependence
Takaaki Koike, Marius Hofert, Haruki Tsunekawa
The classical tail dependence coefficient (TDC) may fail to capture non-exchangeable features of tail dependence due to its restrictive focus on the diagonal of the underlying copu…
