Canonical correlation statistics for testing the cointegration rank in a reversed order

Breitung, Jörg - 1998

In this paper a Canonical Correlation Analysis (CCA) is used to test the hypothesis r = r0 against the alternative r … to construct a confidence set for the cointegration rank. As the latter test, our tests are based on the eigenvalues of a … to Johansen's LR tests for determining the cointegration rank. …

Estimating covariance matrices using estimating functions in nonparametric and semiparametric regression

Carroll, Raymond J.; Iturria, Stephen J.; Gutierrez, … - 1997

We use ideas from estimating function theory to derive new, simply computed consistent covariance matrix estimates in nonparametric regression and in a class of semiparametric problems. Unlike other estimates in the literature, ours do not require auxiliary or additional nonparametric...

Common factors governing VDAX movements and the maximum loss

Härdle, Wolfgang; Schmidt, Peter - 2000

Based on daily VDAX data this paper analyzes the factors governing the movements of implied volatilities of options on the German stock index DAX. Using Principal Components Analysis over the sample period from 1996 to 1997, we derive common factors representing "shift" and "curvature" of the...

Rank tests for nonlinear cointegration

Breitung, Jörg - 1998

A test procedure based on ranks is suggested to test for nonlinear cointegration. For two (or more) time series it is … is no cointegration between the time series, the sequences of ranks tend to diverge, whereas under cointegration the … perform better than their parametric competitors. To test for nonlinear cointegration a variable addition test based on ranks …

Testing for the cointegrating rank of a VAR process with an intercept

Saikkonen, Pentti; Lütkepohl, Helmut - 1998

Testing the cointegrating rank of a vector autoregressive process with an intercept is considered. In addition to the likelihood ratio (LR) tests developed by Johansen and Juselius and others we also consider an alternative class of tests which is based on estimating the trend parameters of the...
