-## Gravity Model
-
-Gravity Models are derived from Newton's Law of Gravity and are used to predict the interaction between a group of populated areas (sources) and a specific target among a group of potential targets, in terms of an attraction factor (weight)
-
-**CDB_Gravity** is based on the model defined in *Huff's Law of Shopper attraction (1963)*
-
-### CDB_Gravity(t_id bigint[], t_geom geometry[], t_weight numeric[], s_id bigint[], s_geom geometry[], s_pop numeric[], target bigint, radius integer, minval numeric DEFAULT -10e307)
-
-#### Arguments
-
-| Name | Type | Description |
-|------|------|-------------|
-| t_id     | bigint[]    | Array of targets ID |
-| t_geom   | geometry[]  | Array of targets' geometries |
-| t_weight | numeric[]   | Array of targets's weights |
-| s_id     | bigint[]    | Array of sources ID |
-| s_geom   | geometry[]  | Array of sources' geometries |
-| s_pop    | numeric[]   | Array of sources's population |
-| target   | bigint      | ID of the target under study |
-| radius   | integer     | Radius in meters around the target under study that will be taken into account|
-| minval (optional)   | numeric     | Lowest accepted value of weight, defaults to numeric min_value |
-
-### CDB_Gravity( target_query text, weight_column text, source_query text, pop_column text, target bigint, radius integer, minval numeric DEFAULT -10e307)
-
-#### Arguments
-
-| Name | Type | Description |
-|------|------|-------------|
-| target_query     | text    | Query that defines targets |
-| weight_column   | text  | Column name of weights |
-| source_query     | text    | Query that defines sources |
-| pop_column   | text  | Column name of population |
-| target   | bigint      | cartodb_id of the target under study |
-| radius   | integer     | Radius in meters around the target under study that will be taken into account|
-| minval (optional)   | numeric     | Lowest accepted value of weight, defaults to numeric min_value |
-
-
-### Returns
-
-| Column Name | Type | Description |
-|-------------|------|-------------|
-| the_geom  | geometry | Geometries of the sources within the radius |
-| source_id | bigint  | ID of the source |
-| target_id | bigint  | Target ID from input |
-| dist      | numeric | Distance in meters source to target (if not points, distance between centroids) |
