Perform Linear Regression in PE

To perform linear regression, follow the steps below:

1. Open the Performance Models window.
2. Right-click the node that represents the data set on which linear regression will be performed and select Analyze Model. The system displays the Analyze Model window with a condition versus age plot of all data points in the data set.
3. Click the Models tab.
4. In the Model Run column, locate the record showing 0-Selected Model.
5. Right-click this record and select Calculate Regression Models. The system performs linear regression analyses for the linear, exponential, inverse exponential, and hyperbolic model types using the entire data set. It then creates four new records in the right pane to contain the results of the analyses, with each record being assigned a Model Run type of 1-Regression.
