A fundamental mechanism is homophily or assortativity, where actors have a higher likelihood to be tied with others having similar values of the variable under study. But there are other mechanisms that may also play a role in how the attribute values of two actors influence the likelihood of a tie. We discuss three additional mechanisms: aspiration to send ties to others having high values; conformity in the sense of sending more ties to others whose values are close to w","authors_text":"Alessandro Lomi, Tom A.B.Snijders","cross_cats":["stat.ME","stat.OT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2018-03-19T21:35:21Z","title":"Beyond Homophily: Incorporating Actor Variables in Actor-oriented Network Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.07172","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:cd8ebd18909cd7198930044811eff6bfb219d4ba2754d1246b0331d4dbbb9abe","target":"record","created_at":"2026-05-18T00:06:04Z","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":"2d449fca91bd1ca50f3484b9c6fc57ba0d05ed9f00a56e2041c5c7bc6d30c1d0","cross_cats_sorted":["stat.ME","stat.OT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2018-03-19T21:35:21Z","title_canon_sha256":"78c442a4627d9f74ddf68fa67fe27725e4bcf4eca72d645602f8333d35a25232"},"schema_version":"1.0","source":{"id":"1803.07172","kind":"arxiv","version":2}},"canonical_sha256":"8176c0eb4a39e50cb539780c252a73789d400e9b627405221ecd805b6994d6eb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8176c0eb4a39e50cb539780c252a73789d400e9b627405221ecd805b6994d6eb","first_computed_at":"2026-05-18T00:06:04.760587Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:04.760587Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+fqcSfr9cJnp6pYdvWbfT9moqIZXVlhNQz6OkvlpyOyfXdrrZbNNWpToC87ZI8tej5eWMogdgfP7FF5NoTl6BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:04.761073Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.07172","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cd8ebd18909cd7198930044811eff6bfb219d4ba2754d1246b0331d4dbbb9abe","sha256:5a10d0a414be5e8bb34ae457a86e892148b685e23ee01d0b88d143db33b151ee"],"state_sha256":"29f4a2f4d67448d85518548ce73128fbecbd932d898060529ff75d763688ca89"}
