You set up the number and definition of model input factors for each stage by double-clicking the inports of the block diagram. See Functions Implemented in the Block Diagram.
The preceding example shows the input setup dialog for the global model. The dialog for the local model contains exactly the same 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 distribution of the input factor space for designing experiments. The available input transformations are 1/x, sqrt(x), log10(x), x^2, log(x). See Transforms for a discussion of the uses of transformations.
Signal
You can set up the signal name in the input factor setup dialog. 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 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.
