| # quant-dif-raw v1 |
|
|
| Raw response data for **"Quantization as a Measurement Invariance Problem: A |
| Differential Item Functioning Analysis of Psychometric Scales in Compressed |
| LLMs"**. |
|
|
| - 189,000 logged administrations of the 50-item IPIP Big-Five Factor Markers |
| to 7 frozen model configurations (Qwen2.5-3B fp16/q8_0/q4_0, Qwen2.5-7B |
| q8_0/q4_0, Llama-3.2-3B q8_0/q4_0), served by Ollama v0.31.1. |
| - Conditions: main experiment (200 personas × 50 items), no-persona |
| distribution sub-experiment (40 samples/item), paraphrase-bank rerun, |
| temperature 0.2/1.0 subsets. |
| - Every JSONL record carries full provenance: model tag, precision label, |
| persona/item ids, per-call seed, temperature, GGUF weight SHA-256, engine |
| version, timestamp, raw response text, parsed 1–5 score, and top-5 token |
| log-probabilities. |
| - Bundle also contains the human-verified paraphrase item bank, the 200-persona |
| pool (deterministic, seed 42), and the model manifest. |
