The automatic region-wise spatially varying coefficient model consists three parts: we first compute the similarity matrix between the exposure-health outcome associations of all spatial units, then segment the whole map into a set of disjoint regions based on the adjacency matrix wit","authors_text":"Chengsheng Jiang, Lance Waller, Shuo Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2015-11-18T20:09:26Z","title":"Automatic Region-wise Spatially Varying Coefficient Regression Model: an Application to National Cardiovascular Disease Mortality and Air Pollution Association Study"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.05924","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:3d446433bc70cfdda169eb1ccdb9ef1bcbf2f0a3c45129364056fce2a1f48754","target":"record","created_at":"2026-05-18T01:26:32Z","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":"0626265ce5453c41a5fccd28434e429cbc1464a4154ba56de67421c18d7326cb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2015-11-18T20:09:26Z","title_canon_sha256":"21391dddcd2b6d7f9ef040adc975cd3906614b2eb7cb7c31c895f80f35ae8bac"},"schema_version":"1.0","source":{"id":"1511.05924","kind":"arxiv","version":1}},"canonical_sha256":"768b6da19a5de43d83ac5680572967e5491e47e89758f597cf421b0a085c3e11","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"768b6da19a5de43d83ac5680572967e5491e47e89758f597cf421b0a085c3e11","first_computed_at":"2026-05-18T01:26:32.292820Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:32.292820Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QqnuW51JH4cxXtx+nAg7A57vHf0G3NAKXPdHzbAoyPwGUkJd1m9JqUztTjYHYKfeP4e+Y8FRzk9q9WQfsQt9DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:32.293556Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.05924","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3d446433bc70cfdda169eb1ccdb9ef1bcbf2f0a3c45129364056fce2a1f48754","sha256:2d2477becc4e462a2b0426f58ec2b301f808aed45d9308114f84350db0b1439d"],"state_sha256":"5b948ca34a56e67d0c8517aacaade01c1313dec9689721609f279b4dd6b24d74"}
