The Beveridge-Nelson decomposition : a different perspective with new results
Gómez, Víctor; Breitung, Jörg - 1998
We show in the paper that the decomposition proposed by Beveridge and Nelson (1981) for models that are integrated of order one can be generalized to seasonal Arima models by means of a partial fraction decomposition. Two equivalent algorithms are proposed to optimally (in the mean squared...

Testing the diffusion coefficient
Kleinow, Torsten - 2002
In mathematical finance diffusion models are widely used and a variety of different parametric models for the drift and diffusion coefficient coexist in the literature. Since derivative prices depend on the particular parametric model of the diffusion coefficient function of the underlying, a...

Estimation and testing for varying coefficients in additive models with marginal integration
Yang, Lijian; Härdle, Wolfgang; Park, Byeong U. - 2002
We propose marginal integration estimation and testing methods for the coefficients of varying coefficient multivariate … regression model. Asymptotic distribution theory is developed for the estimation method which enjoys the same rate of convergence … as univariate function estimation. For the test statistic, asymptotic normal theory is established. These theoretical …

Comparison of bootstrap confidence intervals for impulse responses of German monetary systems
Benkwitz, Alexander; Lütkepohl, Helmut; Wolters, Jürgen - 1999
It is argued that standard impulse response analysis based on vector autoregressive models has a number of shortcomings. Although the impulse responses are estimated quantities, measures for sampling variability such as confidence intervals are often not provided. If confidence intervals are...
