The purpose of this paper is to give a systematic account of the maximum likelihood inference concerning cointegration … vectors in non-stationary vector value autoregressive time series with Gaussian errors. The hypothesis of r cointegration … vectors is given a simple parametric formulation in terms of cointegration vectors and their weights. We then estimate and …

This paper gives a systematic application of maximum likelihood inference concerning cointegration vectors in non … dummies. The hypothesis of cointegration is given a simple parametric form in terms of cointegration vectors and their weights … related to the weights. Tests for the presence of cointegration vectors, both with and without a linear trend in the non …

We consider the nonstationary fractional model Δ^{d}X_{t}=ε_{t} with ε_{t} i.i.d.(0,σ²) and d1/2. We derive an analytical expression for the main term of the asymptotic bias of the maximum likelihood estimator of d conditional on initial values, and we discuss the role of the initial values...

This paper discusses model-based inference in an autoregressive model for fractional processes which allows the process to be fractional of order d or d-b. Fractional differencing involves infinitely many past values and because we are interested in nonstationary processes we model the data...
