Inc. All Rights Reserved. You'll find nonlinear regression most useful if you understand the models you have chosen. The best way to do this is to simulate a curve and then see what happens when you alter a parameter. Viewing graphs of simulated curves is a great way to learn about equations.
Prism can add Gaussian random error to each point in the simulated curve.
This can help you test analysis methods. Create a curve with random error, and then analyze the simulated data. To simulate a curve, start from a data table or graph. Click the Analyze button, select built-in analyses, and then select Simulate Theoretical Curve from the list of curve analyses. Select an equation, enter a value for each parameter, and a range of X values.
