-### Moran's I
+## Name
+
+CDB_AreasOfInterest -- returns a table with a cluster/outlier classification, the significance of a classification, an autocorrelation statistic (Local Moran's I), and the geometry id for each geometry in the original dataset.
+
+## Synopsis
+
+```sql
+table(numeric moran_val, text quadrant, numeric significance, int ids, numeric column_values) CDB_AreasOfInterest(text query, text column_name)
+
+table(numeric moran_val, text quadrant, numeric significance, int ids, numeric column_values) CDB_AreasOfInterest(text query, text column_name, int permutations, text geom_column, text id_column, text weight_type, int num_ngbrs)
+```
+
+## Description
+
+CDB_AreasOfInterest is a table-returning function that classifies the geometries in a table by an attribute and gives a significance for that classification. This information can be used to find "Areas of Interest" by using the correlation of a geometry's attribute with that of its neighbors. Areas can be clusters, outliers, or neither (depending on which significance value is used).
+
+Inputs:
+
+* `query` (required): an arbitrary query against tables you have access to (e.g., in your account, shared in your organization, or through the Data Observatory). This string must contain the following columns: an id `INT` (e.g., `cartodb_id`), geometry (e.g., `the_geom`), and the numeric attribute which is specified in `column_name`
+* `column_name` (required): column to perform the area of interest analysis tool on. The data must be numeric (e.g., `float`, `int`, etc.)
+* `permutations` (optional): used to calculate the significance of a classification. Defaults to 99, which is sufficient in most situations.
+* `geom_column` (optional): the name of the geometry column. Data must be of type `geometry`.
+* `id_column` (optional): the name of the id column (e.g., `cartodb_id`). Data must be of type `int` or `bigint` and have a unique condition on the data.
+* `weight_type` (optional): the type of weight used for determining what defines a neighborhood. Options are `knn` or `queen`.
+* `num_ngbrs` (optional): the number of neighbors in a neighborhood around a geometry. Only used if `knn` is chosen above.
+
+Outputs:
+
+* `moran_val`: underlying correlation statistic used in analysis
+* `quadrant`: human-readable interpretation of classification
+* `significance`: significance of classification (closer to 0 is more significant)
+* `ids`: id of original geometry (used for joining against original table if desired -- see examples)
+* `column_values`: original column values from `column_name`
+
+Availability: crankshaft v0.0.1 and above
+
+## Examples
+
+```sql
+SELECT
+  t.the_geom_webmercator,
+  t.cartodb_id,
+  aoi.significance,
+  aoi.quadrant As aoi_quadrant
+FROM
+  observatory.acs2013 As t
+JOIN
+  crankshaft.CDB_AreasOfInterest('SELECT * FROM observatory.acs2013',
+                                 'gini_index')
+```
+
+## API Usage
+
+Example
+
+```text
+http://eschbacher.cartodb.com/api/v2/sql?q=SELECT * FROM crankshaft.CDB_AreasOfInterest('SELECT * FROM observatory.acs2013','gini_index')
+```
+
+Result
+```json
+{
+  time: 0.120,
+  total_rows: 100,
+  rows: [{
+    moran_vals: 0.7213,
+    quadrant: 'High area',
+    significance: 0.03,
+    ids: 1,
+    column_value: 0.22
+  },
+  {
+    moran_vals: -0.7213,
+    quadrant: 'Low outlier',
+    significance: 0.13,
+    ids: 2,
+    column_value: 0.03
+  },
+  ...
+  ]
+}
+```
