The unknown mean of the data generating process is modelled as a piecewise linear function of time with an unknown number of change-points. We develop a Bayesian approach to infer the joint posterior distribution of the number and position of change-points as well as the unknown mean parameters. A-priori, the proposed model uses an overfitting number of mean parameters but, conditionally on a set of change-points, only","authors_text":"Elaine Bignell, Magnus Rattray, Michael Bromley, Norman van Rhijn, Panagiotis Papastamoulis, Takanori Furukawa","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2017-09-18T18:14:10Z","title":"Bayesian detection of piecewise linear trends in replicated time-series with application to growth data modelling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.06111","kind":"arxiv","version":3},"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":"sha256:8cef1e9a5974c0c47c7b8f4b204865c2e8cfb59fdbd71798b68f853b6b53b398","target":"record","created_at":"2026-05-17T23:39:32Z","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":"06422556f39fe7ccbf2b6df0cbb3c60f81328d2f6280c6d6eef0683e8a9496d6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2017-09-18T18:14:10Z","title_canon_sha256":"ecd3de71c38bb3cee6ff00a8a57fb505b506ae5e3f181655dfb715a2960010c3"},"schema_version":"1.0","source":{"id":"1709.06111","kind":"arxiv","version":3}},"canonical_sha256":"35fd9a887ae2c976763ac1906825d0d4549d9f7907fd7f377c9510dee4513d58","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"35fd9a887ae2c976763ac1906825d0d4549d9f7907fd7f377c9510dee4513d58","first_computed_at":"2026-05-17T23:39:32.549025Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:39:32.549025Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QNtFryuMgERDxNDyFBnYstJLq5+8MPR3zxMxdunTBWvB6qfGtsRNmp41y3H1Hl8hruCeBzjHd6+ZqZp5A2adDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:39:32.549809Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.06111","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8cef1e9a5974c0c47c7b8f4b204865c2e8cfb59fdbd71798b68f853b6b53b398","sha256:7f1b8578318d3b843d0a1b1a1772b97d3ead38b91982497c905bee4949d052dd"],"state_sha256":"03490e2322d07312b14e1fddb6eaabd95809f0721c16344c4e3466d8fe48e213"}
