How accurate has this been?
| Horizon | Tests | Avg. error | Naive error | In 80% range |
|---|---|---|---|---|
| 12 months | 5 | 2.10 pp | 3.26 pp | 80% |
| 24 months | 4 | 1.80 pp | 4.25 pp | 75% |
| 36 months | 3 | 1.22 pp | 4.85 pp | 100% |
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
