Proportional Hazards Diagnostic Results for Cox and Weibull AFT Models

Diagnostic results for testing the proportional hazards assumption in Cox models and a list of models where Weibull accelerated failure time estimates were preferred. The dataset was authored by Wenhan Yang and last updated on June 2, 2026. It is a small dataset, 12.4 KB in size, and is available in XLSX format.

Use Cases

• Validating the proportional hazards assumption for published Cox models based on diagnostic results.
• Identifying survival models where Weibull accelerated failure time estimates were the preferred choice.
• Comparing model diagnostics across different studies or clinical trials.
• Teaching or demonstrating methods for survival model diagnostics and selection.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• File size is 12.4 KB, making it quick to download and inspect.
• Last update timestamp is precisely recorded as 2026-06-02 17:33:56.
