Symmetric real matrices are introduced whose traces--the sums of their eigenvalues--are equal to the Allan variances, in overlapping or non-overlapping forms, as well as for the corresponding forms of the modified Allan variance. Diagonalization of these matrices leads to expressions for the probability distributions for observing a variance at an arbitrary value of the sampling or averaging interval $\\tau$, and","authors_text":"Neil Ashby","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/publicdomain/","primary_cat":"physics.data-an","submitted_at":"2011-03-25T18:59:21Z","title":"Discrete simulation of power law noise"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1103.5062","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":"sha256:6ca66185fbe6c21d8f98158a32b5ba0bd025284f8636d6fd66dc8ea477cee465","target":"record","created_at":"2026-05-18T04:25:48Z","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":"2939c921745e5ae4e1dd6a6a31816ac91e9f872137d38678f0b5ab5bbf73853d","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/publicdomain/","primary_cat":"physics.data-an","submitted_at":"2011-03-25T18:59:21Z","title_canon_sha256":"a76f4815198d66ba63ed47d06fa42e375f08d281c611abf8549833484d15152a"},"schema_version":"1.0","source":{"id":"1103.5062","kind":"arxiv","version":1}},"canonical_sha256":"b9949bad442e304a658e3c4543fc8427070b5eefd1e960e21d47a508d8c4b8fd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b9949bad442e304a658e3c4543fc8427070b5eefd1e960e21d47a508d8c4b8fd","first_computed_at":"2026-05-18T04:25:48.086923Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:25:48.086923Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jbetdnWefy/HLmnI7TO+fxnWPJazqorV4EF5IOBDwaHchHaVd73s/3ICY07TUx/TxF0GXBGWoUzWsG08GcCgDg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:25:48.087347Z","signed_message":"canonical_sha256_bytes"},"source_id":"1103.5062","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6ca66185fbe6c21d8f98158a32b5ba0bd025284f8636d6fd66dc8ea477cee465","sha256:77d91e10095def071c7befacbe5d700caaf8463295715cb31fa9bf0c05096171"],"state_sha256":"c9f9b760af3389f80eca005c5c8676e09cae56c57c954194c3c7c28bb8b22d87"}
