All Implemented Interfaces:

FitsElement
```
public class RandomGroupsData
extends Data
```
This class instantiates FITS Random Groups data. Random groups are instantiated as a two-dimensional array of objects. The first dimension of the array is the number of groups. The second dimension is 2. The first object in every row is a one dimensional parameter array. The second element is the n-dimensional data array.
