Two algorithms have been applied to this Bayes network; one of them is a message-passing algorithm, developed by Pearl [55] to update the probabilities in the various linked networks using conditioning methods and the second one is that the exact inference algorithm, developed by Lauritzen and Spiegelhalter [56] for local probability calculations in the graphical structure.

The probabilities in the Bayes network can represent both objective and subjective information.

Some of these studies can be referred as Bayes networks [5], rough sets [6], and artificial neural networks [7] which are the examples of such studies.

Oracle Data Mining algorithms, including Naive Bayes, Adaptive

Bayes Network and Support Vector Machines, appear as nodes in the Clementine interface.

In drawing a Bayes network, in contrast, these generalizations tend to disappear into the conditional probability tables for the nodes.

The suggested modifications to the Wigmore structure make a Wigmore Chart more closely resemble a Bayes network. This need not cause alarm, because computer software is available to handle any of the calculations.

These include decision trees, influence diagrams, and Bayes networks. These quantitative techniques assist the analyst not only in describing the problem and communicating information about structure, but also in calculating the effect of the truth of one proposition or piece of evidence on the plausibility of others.

It is a snapshot of a problem at a particular instant in time and thus, as has been pointed out by many researchers, it fails to capture the dynamic, even messy, nature of real-life problems.(57) Bayes networks enable one to process information and to move from a description of the problem predata to a description of the problem postdata.

According to the results of the calculations, the variable describing the economy which in the period 2000-2013 was the most frequently reported in Bayes networks describing the relationship of the size of general government sector was the parameter that is called gross domestic product in current prices per inhabitant (GDP per inhabitant).

Subsequet positions were taken by the following ratios: FDI--foreign direct investment (million USD)--39 occurrences in networks, retail sales--dynamic index of turnover (total 2010 = 100)--37 occurrences, growth rates of GDP (percentage change)--36 occurrences, as well as inward FDI flows (million USD)--32 occurrences in Bayes networks and potential output of total economy (million euro)--30 occurrences.

There were seven ratios that gained five occurrences in Bayes networks. These were: inward FDI flows (million USD) in year 2012, potential output of total economy (million euro) in year 2000 and 2005, potential output of total economy (dynamic annual average rate of growth-percentage) in year 2010, as well as gross domestic product in current prices per inhabitant-dynamic (percentage change) in year 2004, harmonized indices of consumer prices (HICPs) (annual average rate of change) in year 2013, outward FDI flows (million USD) in year 2000 and unemployment rate (in %) in 2009.

More complex interactions between predictors may be represented by augmented naive

Bayes networks by allowing directed edges (probabilistic dependencies) between predictors, dispensing with the strong independence assumption of naive Bayes.
