The best posterior probability model could be different from the actual causal model
Proceedings of the 2011 ORSSA Annual Conference
September 18, 2011
An example is shown that the best posterior probability model, as found by the Cooper and Herskovits equation, is not always the causal model. This involves moving from a causal model, to a frequency distribution, to a correlation matrix and back to a model. The elimination heuristic, utilising independence relations, is introduced as a ?first step towards getting the actual causal model. At...

Efficient Value-at-Risk Estimation
International Conference on Future Computer and Communication, 3rd (ICFCC 2011)
In economics and finance, the Value-at-Risk (VaR) is a measurement of the maximum loss not exceeded with a given probability over a specified time. The VaR is an important measurement, as it gives a financial institution with confidence the maximum loss it can incur over time. In this paper, we briefly appraise general VaR measures. Subsequently, we introduce the idea of using the market...

The causal structure was then tested on a holdout sample. Return on shares was estimated based on various accounting attributes over the preceding five years, using a four state version of Pearl’s algorithm. None of the attributes were...
