Data Plotter and Curve Fitter
|
|
Description
|
This program plots data points then gives you a choice of regression types to fit a curve to the data. This update changes the method of data input and improves the editing process. x,y coordinates of points may be entered one at a time or an existing 2 column matrix can be entered. Datafit() includes all regression types on the TI-89 as well as a polynomial regression program, Polyfitn(), which allows you to choose the degree of the polynomial. It's easy to try various regression types and see the results quickly. Even if you don't need to fit a curve to the data, it's a quick way to plot data.
