Welcome to GeNIe manual, Version 2.2.4, Built on 4/3 /2018

This manual is available in ChM, pdf and html formats all available at

httpsupportbayesfusion.com/docs/

CHM version of geNIe manual is also distributed with GeNIe

An entrepreneur Martin Le blanc tweeted a few years ago a user interface is like a

joke. Ifyou have to explain it, it's not that good. While one might criticize this

analogy on several grounds, the Tweet stresses the idea that a user interface has to

be intuitive and transparent. This has been the leading thought over the many years

of the development of geNle's interface. We believe that this manual may turn out to

be superfluous for many users. Still, there are many ways in which people learn and

some of our users will find it useful. Some users may find it handy to use the search

functionality in case they encounter a problem. Others, familiar with the

methodology, may want to read through the section Using GeNIe, which describes

various geNIe modules. Yet others, may want to the treat this manual as a handbook

for decision-theoretic methods

If you are new to genie and would like to start with an informal, tutorial-like

introduction, please start with the Hello GeNIe!section. If you are an advanced

user,please browse through the Table of Contents or search for the topic of your

interest
