In particular, we consider the duplication attachment (DA) model which has a likelihood function that typically cannot be evaluated in any reasonable computational time. We consider a number of importance sampling (IS) and sequential Monte Carlo (SMC) methods for approximating the likelihood of the network model for a fixed parameter value. It is well-known that for IS, the relative variance of the likelihood estimate typically grows at an expo","authors_text":"Ajay Jasra, Junshan Wang, Maria De Iorio","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.CO","submitted_at":"2013-06-19T12:04:02Z","title":"Computational Methods for a Class of Network Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1306.4508","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:b1cd29c3a610df63649ad3b914da41c31bfc02ed4128720fa7359094257a8088","target":"record","created_at":"2026-05-18T03:20:34Z","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":"132759dc9ff9bbe54de9264e430afc124d3b35adb59079bd988a0dac5cb39bd4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.CO","submitted_at":"2013-06-19T12:04:02Z","title_canon_sha256":"40c812b5f630e2c6bd257589ad61f5c5990238f683aa4c0d0e31e3d02382fbcd"},"schema_version":"1.0","source":{"id":"1306.4508","kind":"arxiv","version":1}},"canonical_sha256":"25bba7877db29350ee3f868f59094144e2224a11df3f93c290ae795574b7066b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"25bba7877db29350ee3f868f59094144e2224a11df3f93c290ae795574b7066b","first_computed_at":"2026-05-18T03:20:34.212018Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:20:34.212018Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hsItXQPtGFOur+q7U9FacTNxeb4aWOM5eWldt7fQuYMiQfAMc/g6lO2uQUvrESrHXWvr3g5Q+gqmAOUBvV0jDA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:20:34.212807Z","signed_message":"canonical_sha256_bytes"},"source_id":"1306.4508","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b1cd29c3a610df63649ad3b914da41c31bfc02ed4128720fa7359094257a8088","sha256:adba0a376d052e7e9535a4b9e6896be18ee54fc3e91ed56b80f555fca423dc50"],"state_sha256":"c42d532554d4db1a186aaa0c0bc2f4523981813a830a45f0acce6ad5b7a9e08e"}
