matter

Matter builds 23 machine learning models predicting outcomes across four domains: affordability and family, benefits enrollment, employment, and health.

Each model page includes key metrics, decile lift charts, feature importance, and prediction distributions.

Every classifier score also comes with a likelihood segment: Most likely, Somewhat likely, or Least likely. The segments come in their own segments table, under the same column names as the scores. Most likely holds the top X of records by score, where X is the model’s prevalence (its mean score) up to a cap of 0.33. Somewhat likely holds the next X, and Least likely holds the rest.

A machine-readable catalog of these models, with the same metrics, is at models.json.
