Linux Community at Batam, Indonesia has launched a web application dedicated for educational research by Indonesian teachers. We call it INFER: Integrated Networks For Educational Research (http://infer.gelora-batam.org). It is a Rich Internet Application developed using Ext-GWT, deployed on Tomcat5 and backed by PostgreSQL 8.4 (for its CTE feature). Statistic Probability Density function is calculated within stored procedure written in C, to wrap library provided by GSL (GNU Scientific Library).

At this moment, the service provides analytical tools for: Correlation and One way Analyses Of Variance (ANOVA) study, as well as Exams Item Validation tool (as online alternative for ITEMAN.EXE by Assessments Systems Corporation).

The project will be continually enhanced by Batam Linux Community for more analytical tools.
