In order to calculate the overall probability, p, of a single occurrence of the dependent variable the program combines the input probability (P0) with the applicable factor weights from each of the significant factor groups in the model (P1, P2,...,Pn) according to the formula:
P0 x P2 x...Pn
P = -----------------------------------------
[Po x ...x Pn] + [(1-P0) x ...(1-Pn)]
