# Local Geary

Local geary is a type of LISA that focuses on squared differences/dissimilarity. A small value of the local geary statistics suggests positive spatial autocorrelation, whereas large values suggest negative spatial autocorrelation. For more details, please read: <http://geodacenter.github.io/workbook/6b_local_adv/lab6b.html#local-geary>

## localGeary()

```sql
function localGeary(
    WeightResult w,
    Array val,
    Number permutations, 
    String permutation_method,
    NUmber significance_cutoff, 
    Number seed)
```

### Arguments

| Name                 | Type           | Description                                                                                                |
| -------------------- | -------------- | ---------------------------------------------------------------------------------------------------------- |
| w                    | *WeightResult* | the WeightResult object created from weights function                                                      |
| val                  | Array          | the values of a selected variable                                                                          |
| permutations         | Number         | the number of permutations for the LISA computation. Default: 999.                                         |
| permutation\_method  | String         | the permutation method used for the LISA computation. Options are 'complete', 'lookup'. Default: 'lookup'. |
| significance\_cutoff | Number         | the cutoff value for significance p-values to filter not-significant clusters. Default: 0.05.              |
| seed                 | Number         | the seed for random number generator used in LISA statistics. Default: 123456789.                          |

### Return

| Type       | Description                                                                                                                  |
| ---------- | ---------------------------------------------------------------------------------------------------------------------------- |
| LisaResult | The LisaResult object contains the results of LISA computation: *pvalues, clusters, lisa\_values, neighbors, labels, colors* |
