1.2 What can glmlab do?

MATLAB is a powerful computational tool that can be programmed to perform practically any numerical task. MATLAB has some basic statistical procedures built-in (for example, hist, mean, median and std). More statistical procedures are available--at extra cost--in the Statistics Toolbox.  glmlab extends MATLAB's statistical capabilities without needing the Statistics Toolbox, allowing the user to perform tasks such as:

• simple linear regression;
• multiple regression;
• weighted regression;
• log-linear models;
• logistic regression;
• other generalised linear modelling techniques; and
• residual plots.

glmlab also allows the user to save models between sessions, and returns a number of variables to the workspace for further analysis (see Section 3.5).
