Viewing Sensitivity Analysis Results

Once you have specified a result, added one or more independent variables, and defined the ranges for the independent variables, you can carry out several different types of sensitivity analysis. 

GoldSim provides four types of analysis and display:

   Central Value Result;

   Tornado Chart;

   X-Y Function Chart; and

   Result Data Display.

These are discussed in the  topics below.

   Note: The sensitivity analyses discussed here produce graphical and tabular outputs created by changing one variable at a time, while holding all other variables constant.  GoldSim also provides a second type of sensitivity analysis in which statistical sensitivity measures are computed by analyzing the results of multiple realizations of the model where all of the Stochastic variables are simultaneously sampled each realization.

   Note: During the sensitivity analysis, each run is treated as a deterministic simulation.  You cannot run a sensitivity analysis if your Monte Carlo settings are specified to run multiple realizations.  The settings must be specified to either run a deterministic simulation or a single probabilistic simulation (in which case it will automatically be treated as a deterministic simulation).

   Warning: Warning messages are not displayed when running a sensitivity analysis (although fatal error messages are). 

   Warning: When running a sensitivity analysis, Interrupt messages are never displayed.  Moreover, unless the Specify Action When Message is off or cannot be shown field in the Interrupt is set to "Continue" or "Skip remainder of current Realization and Continue" (or the Interrupt is disabled), any triggered Interrupts will result in a fatal error.
