Abstract
The vector autoregressive (VAR) model has been used to describe the
dependence within and across multiple time series. This is a model for
stationary time series which can be extended to allow the presence of a
deterministic trend in each series. Detrending the data either parametrically
or nonparametrically before fitting the VAR model gives rise to more er
