| Stats | () | constructor |
public function Stats(data:Array, field:String = null, comparator:Function = null, copy:Boolean = true)Creates a new Stats instance using the given input data. If the field argument is null, it is assumed that the input data array directly contains the values to analyze. If the field argument is non-null, values will be extracted from the objects in the input array using the specified property name.
Parametersdata:Array — an input data array. The data to analyze may be
contained directly in the array, or may be properties of the
objects contained in the array.

| equal | () | method |
public static function equal(a:*, b:*):Boolean
Tests for equality between two values. This method is necessary
because the == operator checks object equality and
not value equality for Date instances.
a:* — the first object to compare
|
|
b:* — the second object to compare
|
Boolean |
| DATE | constant |
public static const DATE:int = 1Constant indicating date/time values.
| NUMBER | constant |
public static const NUMBER:int = 0Constant indicating numerical values.
| OBJECT | constant |
public static const OBJECT:int = 2Constant indicating arbitrary object values.
