Statistical Distributions

You will need a java plugin for this web page to work properly. If you don't have one, you can get one from Sun Microsystems. Some java plugins, notably the ones from Microsoft, but also some older plugins won't work with the java applet on this page.

You may freely download and use the source code for the applets:
Normal distribution;
Student t distribution;
Chi-square distribution;
Cumulative binomial distribution;
Calculator.
It is written in Java, though Flash would probably be better, at least for the distributions. If you want to modify any, try starting with the t distribution: the others are hacked from it.
