For Cox regression coefficients, we develop private partial-likelihood-ratio and score-type tests, including a private calibration procedure for the rejection threshold. For cumulative hazard functions, we propose a private distributed two-sample test. Across these problems, we prove differential privacy and finite-sample testing guarantees, as well as minimax lower bounds.","weakest_assumption":"The approach assumes that the underlying survival data follows standard right-censored models (such as Cox proportional hazards) and that a private calibration procedure for rejection thresholds can be implemented without invalidating the finite-sample guarantees, though the abstract provides no details on how calibration interacts with censoring or model misspecification."}},"verdict_id":"780d28f2-0474-4145-8129-a457f7adbfbd"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:acbca297f37bed9475e40f54db74654005919e90cb04927684bd8ab93bac52a5","target":"record","created_at":"2026-05-20T00:03:29Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"09655a10fdb9cb94bc1d5b7f93b4df85572ab140d8d52eb4aa17919d354d1b4a","cross_cats_sorted":["stat.ME","stat.TH"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.ST","submitted_at":"2026-05-16T09:41:49Z","title_canon_sha256":"eddef2864c0952d3405a003fcb2793d417cd6840b31a4f5aa60002df64ffd3ff"},"schema_version":"1.0","source":{"id":"2605.16906","kind":"arxiv","version":1}},"canonical_sha256":"126669611dbd6384ef12ea5d247d79899bda2646e1597a913897c08620c05fa8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"126669611dbd6384ef12ea5d247d79899bda2646e1597a913897c08620c05fa8","first_computed_at":"2026-05-20T00:03:29.465006Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:03:29.465006Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8Kn+YplR9hl/9nNB0ZdKdDNqM6rLLri15sQfXWJH05b5oSmBpwfzc+2xS+zz8vZlN9Ebv5m7E7KFpIPQMteoAg==","signature_status":"signed_v1","signed_at":"2026-05-20T00:03:29.465678Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.16906","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:acbca297f37bed9475e40f54db74654005919e90cb04927684bd8ab93bac52a5","sha256:165fe871f2e21d7b5c89d450b2d8ef719caea2868e938867a80437b24adf344f"],"state_sha256":"31de184ae8cc71b5e26bbd96de3f2326102ba55fc22599db88a4f963258d5272"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"lPnYGiAu1mrTZtUiPWyhIu4U14zti6T8VR16TlR155zwAaOqW+mo03sX2R+hJqUYDBiaXK33HvYz/puDVIBdBg==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-21T16:30:54.967777Z","bundle_sha256":"4dc52d50329fd5c008bc68388ba13b17b3f5bfc0e6fc0473d4d430e9ea3f9673"}}
