This paper extends the multivariate index autoregressive model by Reinsel (1983) to the case of cointegrated time … series of order (1, 1). In this new modelling, namely the Vector Error-Correction Index Model (VECIM), the first differences … fewer than the variables, the VECIM achieves a substantial dimension reduction w.r.t. the Vector Error Correction Model. We …
