Methodology
Each analysis was run in both IBM SPSS Statistics 29.0.2 and Statory using a real survey dataset (N=600, 91 variables) with identical variable selections, options, and parameters.
Key statistics were compared to the third decimal place. An engine is marked "Verified" when all core statistics match within rounding tolerance (Β±0.001).
Statory backend: Python 3.11 + NumPy/SciPy/scikit-learn
