# pre_test — Historical Financial Forecasting MCQ

A 5,443-question multiple-choice benchmark built from **50 US macro / market indicators**
(FRED, 1999–2026). Every correct answer is a **real historical value** independently
re-derivable from raw FRED data — not model-generated.

The dataset is designed to **separate genuine forecasting from memorized recall**: by
comparing a model's accuracy across years (especially 2026, which is past most models'
training cutoff and acts as a clean baseline), and across "blind" vs "revealed" framings
of the same shock event.

## Composition

| `condition` | count | what it tests |
|---|---|---|
| `forecast` | 3,297 | periodic numeric forecast of an indicator (recurrent) |
| `blind`    | 1,073 | aftermath of a market shock, **event name hidden** — clean recall probe |
| `revealed` | 1,073 | the same question, **event name given** — situational reasoning |

`blind` and `revealed` rows are paired 1:1 via `pair_id` (same options, same answer).
Answer letters are balanced: A/B/C/D ≈ 25% each.

## Fields

**Input to the model:**
- `question` — the full prompt, options already appended.
- `options` — the four `"A) …"` strings (also for programmatic use).

**The answer:**
- `answer_letter` — `"A"`/`"B"`/`"C"`/`"D"`.
- `answer_raw` — the numeric value of the correct option (e.g. `"+0.32pp"`).

**Metadata / analysis labels (NOT shown to the model):**
- `condition` — `forecast` / `blind` / `revealed` (the 3 experiment types above).
- `subtype` — `recurrent` / `shock_aftermath`.
- `forecastType` — `Recurrent` / `Non-Recurrent`.
- `indicator` — FRED series id (e.g. `CPIAUCSL`).
- `transform` — `level` / `yoy_pct` / `yoy_pp`.
- `target_period`, `info_cutoff` — what is being predicted, and the information cutoff
  (strictly before the target → it is forecasting, not lookup).
- `unit`, `year`.
- `pair_id`, `event_label`, `event_date` — present on shock rows; link the blind/revealed twins.

## Recommended analysis

1. **Accuracy vs. year** — group by `year`; a cliff at 2026 (→ ~25% chance level) is the
   clean signal that pre-2026 accuracy is partly memorization.
2. **Blind vs. revealed** — join on `pair_id`; a gap suggests the model relies on the event
   name (memory) rather than the pre-cutoff numbers (reasoning). (Auxiliary signal — note
   the date itself can leak event identity.)

## Loading

```python
from datasets import load_dataset

# all rows
ds = load_dataset("lfqian/pre_test", split="train")

# one year at a time (config "by_year", splits y1999 … y2026)
ds_2008 = load_dataset("lfqian/pre_test", "by_year", split="y2008")

# every year as a DatasetDict
by_year = load_dataset("lfqian/pre_test", "by_year")
```

## Files

- `mcq_all.parquet` — all rows (default config, `train` split).
- `mcq_all.jsonl` / `mcq_all.json` — same data, JSONL and single-array JSON.
- `mcq_<year>.parquet` — per-year files (config `by_year`, splits `y1999`…`y2026`).
- `mcq_<year>.json` — per-year files in JSON.

## Provenance

Indicators and values from the Federal Reserve Economic Data (FRED). Questions, distractors,
and answer-letter balancing generated by the OpenFinArena `competitions_historical`
pipeline. 100/100 stratified audit re-derived every sampled answer from raw FRED.
