## numeric_focus

**usage: common - datatype: object** The *numeric_focus* for a Tag.script is the distribution of the *numeric_focus* attribute over the set of entities defined by the *background* attribute. The *numeric_focus* attribute is mandatory when the analysis method is "numeric-comparison". There is no default value for the *numeric_focus* attribute, therefore an error will be thrown if it is undefined for a "numeric-comparison" analysis. The simple form of the *numeric_focus* attribute is a single numeric variable object.

```
"numeric_focus": {
  "variable_type": "numeric", //A numeric variable object
  "collection": "cccc", //"cccc" is a valid numeric collection name in tag.cortex
  "variable": "vvvv" //"vvvv" is a valid variable name in collection "cccc"
}
```

Alternatively, the *numeric_focus* attribute can be any numeric variable object that compiles to a single numeric variable, such as "numeric-compound".

```
"numeric_focus": {
  "variable_type": "numeric-compound", //A numeric variable object
  "operator": "oooo", //A numeric operator, such as "*" 
  "criteria": [
    {...}, //One or more numeric variable objects
    ...
  ]
}
```
