TCEQ Model Assessment ConsiderationsThis figure highlights TCEQ model assessment considerations and how the TCEQ dose-response assessment considers new data and analyses. The scientific weight of evidence clearly indicates that TCEQ’s assessment conducted using the standard Cox proportional hazards model results in more reliable and reasonable estimates of excess risk than USEPA’s unconventional, overall supra-linear two-piece spline model.https://www.tceq.texas.gov/downloads/toxicology/images/tceq-model-assessment.jpg/viewhttps://www.tceq.texas.gov/downloads/toxicology/images/tceq-model-assessment.jpg/@@images/image-1200-07bb2597cf8e2355a6ff948529c05859.jpeg?v=image
