We establish an asymptotic theory for estimates of the time-varying regression functions. For this general class of models, an important issue in practice is to address the necessity of modeling the regression function as nonlinear and time-varying. To tackle this, we propose an information criterion and prove its selection consistency property. The results are applied to the U.S. Treasury interest rate data.","authors_text":"Ting Zhang, Wei Biao Wu","cross_cats":["stat.TH"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.ST","submitted_at":"2015-03-18T06:13:33Z","title":"Time-varying nonlinear regression models: Nonparametric estimation and model selection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.05289","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":"sha256:6e4c600f54c163c9d4f4922848aa3881f6d56291cc991a6c4deffd0339d1fbef","target":"record","created_at":"2026-05-18T02:21:50Z","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":"4128aa75726cbe1af3425c1cdc23ce859effbb1fe961427927b02f66cd8c7ab3","cross_cats_sorted":["stat.TH"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.ST","submitted_at":"2015-03-18T06:13:33Z","title_canon_sha256":"351cf4a2cf99502493b9b59768a5c1c0e6fa9c9be74aebaff4e46ff9c198253e"},"schema_version":"1.0","source":{"id":"1503.05289","kind":"arxiv","version":1}},"canonical_sha256":"0926280d615106cdf62ae2d55177d347c3e5a3f2df5aaeb150d73e09a55c936c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0926280d615106cdf62ae2d55177d347c3e5a3f2df5aaeb150d73e09a55c936c","first_computed_at":"2026-05-18T02:21:50.863094Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:21:50.863094Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QpLs7mPP/LYwt1b/3UzR5fpP9YRv/Jwc/9gIP8ZJwc/7vK0EAfexIKr/wtQ/p9Yorez3BwAG4dQdK4TR9fnIBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:21:50.863692Z","signed_message":"canonical_sha256_bytes"},"source_id":"1503.05289","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6e4c600f54c163c9d4f4922848aa3881f6d56291cc991a6c4deffd0339d1fbef","sha256:082af7e386ffe4c257c0b89d47807030ffb0ad5be108ae6895b32bfb70cb7cc8"],"state_sha256":"cd97ed665cfb457d71198354dd696f8680e06628377d580a4d55d523bdd8115d"}
