Basic Prop is a java application which can be downloaded as a single, cross-platform, JAR file. It can be found here:
Basic Prop Version1.4 (with thanks To Mudi Jiang for improved functionality!)
This latest version allows hierarchical clustering from within the programme, without using R.
First create a folder within which you wish to work with the simulator. Then right click on the above link, and save the JAR file to that folder.
Before you get going, you will also need some pattern files. These are plain text files that form the basis for supervised learning. Three simple files are provided below. Save these to your folder also. Now double click on the application and you are ready to explore, and move on to the first few sample simulations.
