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
