Title: Analysis Wizard : Specific Algorithm?
Post by: abul on April 05, 2011, 12:50:50
Hi,

I just wanted to check what specific algorithm is used in the Analysis Wizard to calculate the Data Accuracy. As far as I understood, inference algorithms will be used for this purpose.

I am aware of that there are inference algorithms like Kim and Pearl’s Message Passing Algorithm
, Lauritzen Speigelhalter Algorithm etc.

Which of them are used in Hugin Researcher ver 7.3?

Your help will be highly appreciated.

Regards,

Abul

The HUGIN algorithm is the inference algorithm implemented in the HUGIN tool. It is described in:

F. V. Jensen, S. L. Lauritzen, and K. G. Olesen. Bayesian updating in causal probabilistic networks by local computations. Computational Statistics Quarterly, 5(4):269–282, 1990.

You can find more information on propagation of evidence in the HUGIN API Reference Manual chapter 9.
