How accurate has this been?
| Horizon | Tests | Avg. error | Naive error | In 80% range |
|---|---|---|---|---|
| 12 months | 5 | 0.16M | 0.35M | 100% |
| 24 months | 4 | 0.13M | 0.70M | 100% |
| 36 months | 3 | 0.21M | 1.06M | 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; 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
