How accurate has this been?
| Horizon | Tests | Avg. error | Naive error | In 80% range |
|---|---|---|---|---|
| 1 yr ahead | 5 | 4.22 pp | 4.34 pp | 60% |
| 2 yr ahead | 4 | 7.94 pp | 8.97 pp | 25% |
| 3 yr ahead | 3 | 4.87 pp | 6.68 pp | 67% |
We re-ran the model as if standing at past dates, using only the data available then. Avg. error is the mean absolute gap between the median and what happened (percentage points); naive assumes no change from the last value. A well-calibrated 80% range contains about 80% of outcomes. Annual series have few test points, so treat these as rough. Methodology
