Updating Forecasts in Vector Autoregression Models with an Application to the Canadian Banking Industry
Bibliographic record
Abstract
Forecasting firms ’ earnings has long been an interest of market participants and academics. Traditional forecasting studies in a multivariate time series setting do not take into account that the timing of data release for a specific time period of observation is often spread over several days or weeks. This paper focuses on the separation of announcement timing or data release and the use of econometric real-time methods, which we refer to as an updated vector autoregression (VAR) forecast, to predict data that have yet to be released. In comparison to standard time series forecasting, we show that the updated forecasts will be more accurate the higher the correlation coefficients among the standard VAR innovations are. Forecasting with the sequential release of information has not been studied in the VAR framework, and our approach to the six Canadian banks shows its value. By using the updated VAR forecast, we find that the relative efficiency gain is 33 % in the one-step-ahead forecast compared to the ordinary VAR forecast, and 7 % compared to professional consensus forecasts. Thought experiments suggest that if banks ’ order of information release were to change, forecast errors could be substantially reduced. These experiments emphasize that evaluating the release ordering is crucial in determining forecast accuracy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
