+posterior probabilities for relationships between a single predictor variable
+and multiple potential outcome variables, incorporating prior probabilities of
+relationships.  In the context of knockdown experiments, the predictor
+variable is the knocked-down gene, while the other genes are potential
+targets.  It can also be used for differential expression/2-class data.")
