forecast error correction Pledger, Texas

The resulting model is known as a vector error correction model (VECM), as it adds error correction features to a multi-factor model known as vector autoregression (VAR).

However, that's not the important point here.) To use (4) to obtain a forecast, Y*t, for Yt, we would set the residual to zero and use the estimated coefficients and the We'll assume that both of these features of the data have been established by previous testing. JSTOR2231972. The results indicate that the forecast errors can be largely reduced using the proposed method if the proper length of past data is chosen.

Hart, G. F. Numerous previous studies reinforce the need to specify correctly a model’s multivariate stochastic structure. If our ECM includes lags of ΔYt as regressors, as will often be the case, the story changes in a pretty obvious way.
