A mathematical model is an equation that describes a physical, chemical or biological state or process. The goal of nonlinear regression is to fit a model to your data.
•What exactly is a mathematical model?
•Learn from three example models.
•It sure would be nice if models could be chosen by Prism. Why is this not possible?
•When trying to understand a model, here are some tips for figuring out what it means.
•In addition to fitting a model to data, Prism can plot a function, or a family of functions. You choose a function and values for the parameters, and Prism will plot predicted Y values for a range of X values.
