At this point, do one of three things:
• If the model that you want to use already exists in a column of the data table, select the column here,
and then click OK. You are returned to the Nonlinear Path Model Specification. For details about all the
features for that specification, see “Model Specification Details” on page 288.
• If the model that you want to use does not already exist in the data table, you can click the Model
Library button to use one of the built-in models. For details about using the Model Library button, see
the Nonlinear Regression chapter of the Modeling and Multivariate Methods book. After the model is
created, relaunch the Degradation platform and return to the column selection shown in Figure 16.10.
Select the column that contains the model, and then click OK. You are returned to the Nonlinear Path
Model Specification. For details about all the features for that specification, see “Model Specification
Details” on page 288.
• If the model that you want to use is not in the data table, and you do not want to use one of the built-in
models, then you are not ready to use this model specification. First, create the model, relaunch the
Degradation platform, and then return to the column selection (Figure 16.10). Select the column
containing the model, and then click OK. You are returned to the Nonlinear Path Model Specification.
For details about all the features for that specification, see “Model Specification Details” on page 288.
See the Nonlinear Regression chapter of the Modeling and Multivariate Methods book for additional
information.
Model Specification Details
After you select one of the model types and supply the required information, you are returned to the
Nonlinear Path Model Specification window. See Figure 16.11 for the Model Specification that you get after
clicking OK in Figure 16.8.
