Calculation STATBEANS® compute statistics which may then be accessed by user programs or other STATBEANS®. They are JavaBean examples that work with Statgraphics software. What is a JavaBean? It retrieves data from a datasource STATBEAN by specifying one or more column names. Each of our JavaBean examples, or STAT Beans are set up to listen for that datasource's dataChange event, which causes it to request data from the datasource and perform its calculations. Results may then be obtained from the calculation STATBEAN by invoking one of its methods.
