Time varying hierarchical archimedean copulae

Härdle, Wolfgang; Okhrin, Ostap; Okhrin, Yarema - 2010

There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...

Are correlations constant over time? : application of the CC-TRIGt-test to return series from different asset classes

Fischer, Matthias (contributor) - 2007

A new test for constant correlation is proposed. Based on the bivariate Student-t distribution, this test is derived as Lagrange multiplier (LM) test. Whereas most of the traditional tests (e.g. Jennrich, 1970, Tang, 1995 and Goetzmann, Li & Rouwenhorst, 2005) specify the unknown correlations as...
