Stochastic Distribution Types

The types of probability distributions supplied by GoldSim are summarized below:

Distribution Type
Beta
Generalized Beta
BetaPERT
Binomial
Boolean
Cumulative (and log-Cumulative)
Discrete
Exponential
Externally-defined
Extreme Probability
Extreme Value
Gamma
Log-Normal
Negative Binomial
Normal
Pareto
Pearson Type III
Poisson
Sampled Results
Student’s t
Triangular (and log-Triangular)
Uniform (and log-Uniform)
Weibull

The fields that appear in the Parameters section of the dialog will change with the distribution type. As a general rule, you should not specify the parameters of a distribution as a function of time, since GoldSim does automatically resample the distribution unless you specifically instruct GoldSim to do so.

The required inputs for each of the distributions types are summarized in the topics below. An example file which uses all of the Stochastic elements (Distributions.gsm) is in the General Examples/Stochastic folder in your GoldSim directory (accessed by selecting File | Open Example... from the main menu). The mathematical details of each of the distributions are provided in Appendix B of the GoldSim User’s Guide.
