The following describe the syntax for the different available distributions for the various random tools:
- UNIFORM {Minimum}, {Maximum}—A uniform distribution with a range defined by the {Minimum} and {Maximum}. Both the {Minimum} and {Maximum} are of type double. The default values are 0.0 for {Minimum} and 1.0 for {Maximum}.
- INTEGER {Minimum}, {Maximum}—An integer distribution with a range defined by the {Minimum} and {Maximum}. Both the {Minimum} and {Maximum} are of type long. The default values are 1 for {Minimum} and 10 for {Maximum}.
- NORMAL {Mean}, {Standard Deviation}—A Normal distribution with a defined {Mean} and {Standard Deviation}. Both the {Mean} and {Standard Deviation} are of type double. The default values are 0.0 for {Mean} and 1.0 for {Standard Deviation}.
- EXPONENTIAL {Mean}—An Exponential distribution with a defined {Mean}. The {Mean} is of type double. The default value for {Mean} is 1.0.
- POISSON {Mean}—A Poisson distribution with a defined {Mean}. The {Mean} is of type double. The default value for {Mean} is 1.0.
- GAMMA {Alpha}, {Beta}—A Gamma distribution with a defined {Alpha} and {Beta}. Both the {Alpha} and {Beta} are of type double. The default values are 1.0 for {Alpha} and 1.0 for {Beta}.
- BINOMIAL {N}, {Probability}—A Binomial distribution with a defined {N} and {Probability}. The {N} is of type long, and {Probability} is of type double. The default values are 10 for {N} and 0.5 for {Probability}.
- GEOMETRIC {Probability}—A geometric distribution with a defined {Probability}. The {Probability} is of type double. The default value for {Probability} is 0.5.
- NEGATIVE BINOMIAL {N}, {Probability}—A negative binomial distribution with a defined {N} and {Probability}. The {N} is of type long, and {Probability} is of type double. The default values are 10 for {N} and 0.5 for {Probability}.
