In this work, we propose a full Bayesian procedure to analyze fMRI data for individual and group stages. For the individual stage we use a multivariate dynamic linear model (MDLM), where the temporal dependence is modeled through the state parameters and the spatial dependence is modeled only locally, taking the nearest neighbors of each voxel location. For the group stage we take advantage of the posterior distribution of the state para","authors_text":"Carlos Alberto de Bragan\\c{c}a Pereira, Johnatan Cardona Jim\\'enez, Victor Fossaluza","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2018-06-13T21:55:15Z","title":"Full Bayesian Modeling for fMRI Group Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.05281","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:ba692399f9a9b796382c1decfb0b6d0d91bce6202b04242559d02b51615c2729","target":"record","created_at":"2026-05-18T00:13:16Z","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":"1c611f5d08a36181fa0d5246891b4a76bbe6ee145dce844dbe389ba0a5f4ea00","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2018-06-13T21:55:15Z","title_canon_sha256":"3b24ec420c0c4716fe0c9855324bfef7786e4e4972e4c77881cffb37b510fb89"},"schema_version":"1.0","source":{"id":"1806.05281","kind":"arxiv","version":1}},"canonical_sha256":"0556c6c7796cbbfb37c8da661bbefea15a0de617059e36ca5a4100a0521c8ae1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0556c6c7796cbbfb37c8da661bbefea15a0de617059e36ca5a4100a0521c8ae1","first_computed_at":"2026-05-18T00:13:16.532470Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:13:16.532470Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"isDYI9xCUlQBXM7aTQOobaVB+rvaxqJm723828kKX598oi7JHs3Fmnp1UsGF8InNszGggrgW1lTE1n9Ldb6qDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:13:16.533114Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.05281","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ba692399f9a9b796382c1decfb0b6d0d91bce6202b04242559d02b51615c2729","sha256:dad7f2649fd7a911ed5f06d49c3ea43b8dce7ae03ea56fc5ec1ff8901125096c"],"state_sha256":"2218b699a18c02438d960e485ddf9c17f9c0feb7d48cf957eb54b8b5882595f4"}
