The browser An alternative view of a GoldSim model, in which elements are displayed in a tree, and organized either hierarchically, or by type. view of a Stochastic element An element that can be used to quantitatively represent the uncertainty in a model input. is shown below:
Note: Element inputs and outputs are only shown in the browser if you choose to Show Element Subitems (accessed via the browser context menu by right-clicking in the browser).
All Stochastic elements have four outputs.
Note that the Distribution output has a different icon than the other outputs. This is because the Distribution output is a complex output that represents all the statistical information necessary to define a probability distribution A mathematical representation of the relative likelihood of a variable having certain specific values. It can be expressed as a PDF (or a PMF for discrete variables), CDF or CCDF.. It can only be used in several specialized locations.
The number of inputs is a function of the distribution type. If the Stochastic is correlated, it has a Correlated To input, as well as a Factor input (the correlation factor).
Note: If you have specified a quantile or a specified value for the Deterministic Value, this also appears as an input in the browser. In addition, if the Stochastic is explicitly triggered, a number of additional inputs related to triggering also appear.
