|
Initialize | When implemented in a class, initializes an instance of a distribution class. |
|
SetInputValues | When implemented in a class, sets the input values for a distribution. |

Remarks
Each standard data generator that is numeric (Decimal, Money, DateTime, Real, Float, and the integer generators) has a Distribution property. The user can specify the Distribution property to generate data that approximates a statistical distribution curve. The standard distribution options are as follows: Uniform, Normal, Normal Inverse, Exponential, and Exponential Inverse.
If the standard distributions are insufficient, you can create a custom distribution. To create a custom distribution, you must create a class that implements IDistribution or inherits from Distribution. You identify the class as a distribution by decorating it with DistributionAttribute.
You can create a custom designer for a custom distribution, or you can use DefaultDistributionDesigner.
