Input Factor Setup

You set up the number and definition of model input factors for each stage by double-clicking or right-clicking the inports of the test plan block diagram. You can update ranges and symbols and refit existing models.

See Test Plan Level.

The following example shows the input setup dialog box for the global model. The dialog box for the local model contains exactly the same controls.

You can use the following controls:

• Number of Factors

  You can change the number of input factors using the buttons at the top.

• Symbol

  The input symbol is used as a shortened version of the signal name throughout the application. The symbol should contain a maximum of three characters.

• Min and Max Model Range

  This setting is important before you design experiments. The default range is [0.100]. There is usually some knowledge about realistic ranges for variables. If you are not designing an experiment you can use the data range as the model range later, in the data selection stage. In some cases you might not want to use the data range (for example, if the data covers too wide a range, or not wide enough) if you are interested in modeling a particular region. In that case you can set the range of interest here.

• Transform

  You can use input transformations to change the input factor for designing experiments. The available input transformations are 1/x, sqrt(x), log10(x), x^2, log(x).

• Signal

  You can set up the signal name in the input factor setup dialog box. It is not necessary to set this parameter at this stage, as it can be defined later at the data selection stage (as with the range). However, setting the signal name in this dialog box simplifies the data selection procedures, as the Model Browser looks for matching signal names in loaded data sets. When the number of data set variables is large this can save time.
