Method, program product, and apparatus for generating analysis model

摘要

The present invention provides an analysis model generating method for generating an analysis model expressed using a Bayesian network. A analysis model generating method includes selecting a child variable to be added to the analysis model; selecting a plurality of variable candidates to be added to the analysis model as parent variables in causal relationships with the child variable; judging whether each of values indicating the causal relationships between the selected variable candidates and the child variable is high or low, based on the causal relationships between the variable candidates and the child variable; generating an aggregated variable different from the variable candidates by aggregating a plurality of low causal variable candidates; and putting high causal variable candidate and the aggregated variable into the analysis model as the parent variables to the child variable.
