Though most attention has focused on determining lower-bounds on the alpha-diversity i.e. the total number of different species present in the environment, tight bounds on this quantity may be highly uncertain because a small fraction of the environment could be composed of a vast number of different species. To better assess what remains unknown, we propose instead to predict the fraction of the environment that belongs to unsam","authors_text":"Jens Reeder, Manuel Lladser, Ra\\'ul Gouet","cross_cats":["math.PR","q-bio.GN","q-bio.PE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2011-09-14T04:33:07Z","title":"Extrapolation of Urn Models via Poissonization: Accurate Measurements of the Microbial Unknown"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1109.2990","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":"sha256:02d6c23567f8d165e2257c976c909f2fccd6938f4cf712474efe0bbaeada9f19","target":"record","created_at":"2026-05-18T04:13:06Z","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":"136fa78d5977494dd35f09e9b11a5f02564b10b2d9c432dcef5f014025d70d14","cross_cats_sorted":["math.PR","q-bio.GN","q-bio.PE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2011-09-14T04:33:07Z","title_canon_sha256":"376f71e78016c511ac337c4775a219ed216dd53cf93761bd9c18f5f03724b719"},"schema_version":"1.0","source":{"id":"1109.2990","kind":"arxiv","version":1}},"canonical_sha256":"de0bef1549fdd3c24b341f71e76fe6a9be3f97dc649dec2d8caeb1e5f3adf8ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"de0bef1549fdd3c24b341f71e76fe6a9be3f97dc649dec2d8caeb1e5f3adf8ba","first_computed_at":"2026-05-18T04:13:06.532788Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:13:06.532788Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HjozCTASYTmsa0qHMCW7B+v7S9p+x3hxgzeH/XgPhMBKSx2/ZVFrQvseTG/XjRAAVdxiGszjdh3C4l1lQoxaCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:13:06.533247Z","signed_message":"canonical_sha256_bytes"},"source_id":"1109.2990","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:02d6c23567f8d165e2257c976c909f2fccd6938f4cf712474efe0bbaeada9f19","sha256:6d8874ac8b584a247e578cb71293bf67bd1bf7b60f389e9ffa2c27b744197a5a"],"state_sha256":"fb121b01cb692e15704580f94a98f16828faac78f852f42e1525c22d35614918"}
