Example ​

Here is a quick example of using GeoDaLib to apply Local Moran statistics on some example data:

ts
import { localMoran } from '@geoda/lisa';

// exmaple data
const data = [3.0, 3.0, 0.0, 9.0, 8.0, 8.5];
const neighbors = [[1], [0], [], [4, 5], [3, 5], [3, 4]];
const permutation = 99;

// call local moran
const result = await localMoran({ data, neighbors, permutation });
