[EDGE] A grouped calibration test for logistic regression that tolerates a few corrupted records

Read the original on arXiv Statistics ML →

The paper introduces EDGE, a grouped calibration test for logistic regression that remains robust when a few records are corrupted. EDGE projects grouped residuals onto a small basis of calibration shapes, keeping degrees of freedom independent of group count, which allows fine‑grained power or coarse protection against outliers. In simulations and external validation, EDGE matched or exceeded the power of existing tests while maintaining false‑alarm rates below 10% even with corrupted data.

[DeepGOF] Where Does a Logistic Risk Model Fail? An Audited Neural Goodness-of-Fit Test for Model Development and External Validation

DeepGOF-1 is a neural goodness‑of‑fit test for logistic regression that maps residuals over covariate ranks, scores them with a frozen convolutional network, and calibrates the score via parametric bootstrap. It achieves first‑order valid level, offers explicit local power, and outperforms traditional chi‑square and projection tests in simulations and real data, revealing missed interactions and guiding model repairs. In the SUPPORT study, it identified a U‑shaped risk pattern for blood pressure and respiratory rate that standard calibration curves obscured, and it ran in 13 seconds versus hours for competing methods.

A Closed-Form Estimator and Diagnostic Battery for Anchor-Judge Error Correlation, Under a Single-Common-Factor Model

The paper presents a closed‑form estimator for the contamination correlation between anchors and judges under a single‑common‑factor model, requiring at least two judges and two anchors. It introduces a diagnostic battery—including judge‑covariance dispersion, over‑identification tests, a family‑block test, bootstrap confidence intervals, and a weak‑identification screen—to validate the estimator and detect violations. The authors also discuss identification limits for ordinal data and report that real panels have not yet passed the model‑adequacy pre‑test, while simulation studies confirm the estimator’s performance.
