const adapter = new CypherAdapter();
await adapter.connect("bolt://localhost:7687", { user: "neo4j", password: "password" });

Statistical Methods

import { calculateDensity } from './stats/inference';
import { zTestDensity } from './stats/hypothesis';

// Weighted density
const density = await calculateDensity(adapter, "weight");

// Z-test
const { zScore, pValue } = await zTestDensity(adapter, 0.5, 100, "weight");

Importing Data

import { CSVImporter } from './importer';

const importer = new CSVImporter(adapter);
await importer.importNodes("path/to/nodes.csv", "Person");
await importer.importEdges("path/to/edges.csv", "source", "target", "KNOWS", "Person", "Person", "id", "id", "weight");
