Hints on viewing this site

To view in larger or smaller fonts: change the text-size from your browser's view menu

Links that go outside the PEAS site will open in new browser windows, leaving your P|E|A|S window open.

Most links to other parts of the P|E|A|S site will appear in your current window, so you will need to press the back button, or the side menu, to get back to where you were.

A few files in the PEAS site will open as new pop-up windows, and for this your browser will need to allow pop-up windows to be seen.

Information pop-ups signalled by a contain explanations that will appear when you click on them. You can close them by clicking your mouse anywhere on a main P|E|A|S page.

Links on the right hand column go to code or results that shows how techniques are implemented in different statistical packages.
