Statistical Analysis Overview
Use statistical analysis to explore the effects of random combinations of values of selected variables on selected global or local available analysis results. Before a variable is included in a statistical analysis, specify that you intend for it to be used during a statistical analysis. For each variable you must specify the type of distribution (Uniform, Gaussian, Lognormal or User Defined) and the corresponding parameters of the selected distribution.
A statistical analysis is currently limited to using a maximum of 30 variables.
In addition to specifying the variables to use in the statistical analysis and the parameters of the chosen distribution, you must also specify the output quantities of interest. These quantities can be global ones such as previously defined parameters (force/torque, inductance/capacitance, and so on), other named quantities, quantities defined in the field calculator as global (such a domain integral of a certain field quantity) or local (such as field value at a certain location). The calculations performed during the statistical analysis are specified during setup, in a manner similar to other types of analysis in Optimetrics.
Following the analysis the statistical distribution of the output quantities can be visualized in histogram format. To access available reports, after the statistical analysis is complete, right-click the respective Statistical analysis setup and select View Analysis Result.
