Statistics Toolbox

Demos

Introduction

The Statistics Toolbox has demonstration programs that create an interactive environment for exploring the probability distributions, random number generation, curve fitting, and design of experiments functions. Most of them provide a graphical user interface that can be used with your real data, not just with the sample data provided.

The available demos are listed below.

Demo	Purpose
aoctool	Interactive graphic prediction of anocova fits
disttool	Graphic interaction with probability distributions
glmdemo	Generalized linear models slide show
nlintool	Interactive fitting of nonlinear models
polytool	Interactive graphic prediction of polynomial fits
randtool	Interactive control of random number generation
robustdemo	Interactive comparison of robust and least squares fits
rsmdemo	Design of experiments and regression modeling
rstool	Exploring graphs of multidimensional polynomials
stepwise	Interactive stepwise regression

Most of these functions are described below. The nlintool, rstool, and stepwise demos are discussed in earlier sections:

• nlintool: An Interactive GUI for Nonlinear Fitting and Prediction
• rstool: Exploring Graphs of Multidimensional Polynomials
• stepwise: Example: Stepwise Regression
