The focus is on non-Gaussian random fields with Mat\\'ern covariance functions, and in particular we show how the SPDE formulation of a Laplace moving average model can be used to obtain an efficient simulation method as well as an accurate parameter estimation technique for the model. This should be seen as a demonstration of how these techniques can be used, and generali","authors_text":"David Bolin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2012-06-04T13:52:19Z","title":"Spatial Mat\\'ern fields driven by non-Gaussian noise"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1206.0622","kind":"arxiv","version":2},"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":"sha256:12e10b53a7ac0dcb928c9c742456a0e0a52f34fd8abca249e4c3a8728f9cfbad","target":"record","created_at":"2026-05-18T03:53:33Z","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":"e005370a2ca637d9d5c2b86b18affba45cd7622747d6d25ef644c10fde222b5d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ME","submitted_at":"2012-06-04T13:52:19Z","title_canon_sha256":"9915ecce083a51d41b5e43df7761f0f48743bed2085142c723f3021a981cad37"},"schema_version":"1.0","source":{"id":"1206.0622","kind":"arxiv","version":2}},"canonical_sha256":"0a6cf6b9f00b261601d3d2ecc7b7590783aaa566a2b1a3e30070e764f32e5066","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0a6cf6b9f00b261601d3d2ecc7b7590783aaa566a2b1a3e30070e764f32e5066","first_computed_at":"2026-05-18T03:53:33.336093Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:53:33.336093Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"84t3umTjT5DCwduFkPI8tAk60ZSZ81MhHZqpdIm1x7gAnt2rgjdHjFN8KDdUyqIe2rsm4JdjSEOmcOxIDIfaCA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:53:33.336913Z","signed_message":"canonical_sha256_bytes"},"source_id":"1206.0622","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:12e10b53a7ac0dcb928c9c742456a0e0a52f34fd8abca249e4c3a8728f9cfbad","sha256:9c1eb8bd17f4acd860e0500707453d85f51489ec7d29bf2be869918b6dd65e56"],"state_sha256":"2b30d68b34774d436252520f98538007654e8624f2f9fba6bfd6cac186fd5ea5"}
