What actually moves crime?

Now you can prove it.

Using the same causal-inference methods used in peer-reviewed criminology research, we tested three of the biggest levers a department can pull — patrol stops, response times, and search practices — against a full year of real 2025 Nashville stop, crime, and dispatch data. Here's what actually moves the numbers, and what doesn't.

Most analytics platforms find patterns. Sigma Squared finds drivers — the specific factors that don't just correlate with success but actually produce it.


Every model is deterministic, causal, and explainable on demand. The same inputs produce the same outputs every time. When someone asks why, the system answers.

Explainable on demand.
