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.

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.
