Bayesian Analysis Helps Avoid Fatalities in Clinical Drug Trials

Drugs interact in unpredictable ways, and most important, they may simply cause different biochemical reactions from one individual to the next.  Care to guess what the No. 1 cause of acute liver failure is in this country? Acetaminophen, the pain reliever in Tylenol. Click here for the full article in Fortune magazine.

Measuring Your Risks
by Norman Fenton and Martin Neil


By destroying the meteor in the film Armageddon, Bruce Willis saved the world. The probability of the meteor strike was so large, and the consequences so great, that nothing much else mattered except to try to prevent the strike. Combining the ‘probability’ and ‘impact’ of a risk in order to define its ‘size’ is standard practice. But in most cases it’s irrational, and it certainly would not have explained to Bruce Willis and his crew why their mission made sense. To get rational measures of risk you need a causal model (‘risk map’) that links triggers, controls, events, mitigants and consequences.

Customer Showcase

Managing Uncertainty in Microelectronic Obsolescence
QinetiQ are approaching the end of a three-year project using Bayesian analysis to manage the uncertainty associated with monitoring and dealing with obsolescence in microelectronics components.  They used the AgenaRisk engine to do a cost-benefit analysis of different possible ways of dealing with obsolescence incidents.

Using Ranked Nodes in AgenaRisk
Ranked nodes are a very powerful way of encoding the probabilistic relationship between a set of parent nodes and a child node. If all the nodes are defined on subjective scales and there is little quantitative data available to build the child NPT (node probability table), consider making the nodes ranked and then take advantage of a number of special and very useful mathematical expressions.
