Declaration
Function Random_Weibull(const a: Extended): Extended;
| Parameters | 
| a | Parameter for Weibull Distribution. Cannot be 0. | 
| RandomGenerator | Optional Function to use for Uniform Random Number Generator. If omitted, Delphi's Random function is used, and if this is done remember to call Randomize if you don't want repeated values. |
