Including a Variable in a Statistical Analysis
Before including a variable in a statistical analysis, you must specify that you intend to use it during a statistical analysis in the Properties dialog box.
- To include a variable in a statistical analysis:
- If the variable is a design variable, click Twin Builder > Design Properties. You can also access the project variables from a menu in the lower left corner of the following Optimization dialog boxes: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and DesignXplorer Setup. Click Edit Variables > Edit Design Variables.
- If the variable is a project variable, click Project > Project Variables. You can also access the project variables from a menu in the lower left corner of the following Optimization dialog boxes: Parametric, Optimization, Sensitivity, Statistical, Design of Experiments, and DesignXplorer Setup. Click Edit Variables > Edit Project Variables.
The Properties dialog box appears.
- Click the tab that lists the variable you want to include in the statistical analysis.
- Click the row containing the variable
you want to include in the statistical analysis.
Note:
Dependent variables cannot be included in a statistical analysis.
- Select the Statistical option above.
- For the variable you want to include in the statistical analysis, select Include.
The selected variable will now be available for statistical analysis in a statistical setup defined in the current design or project.
Note:
Complex numbers are not allowed for variables to be used in an Optimetrics sweep, or for optimization, statistical, sensitivity or tuning setups.
- Optionally, override the distribution criteria that Optimetrics will use for the variable in every statistical analysis.
