Abstract

The potential influence diagram is a generalization of the standard "conditional" influence diagram, a directed network representation for probabilistic inference and decision analysis [Ndilikilikesha, 1991). It allows efficient inference calculations corresponding exactly to those on undirected graphs. In this paper, we explore the relationship between potential and conditional influence diagr...

Nichel and Welch (9, 10), Broquisl et al. (1), Hill and Scott (6), and Welch et al. (16) found that ascorbic acid, a reducing agent, enhanced the for mation of citrovorum factor (CF) from folie acid (PGA). Nichel and Welch (9, 10), indicated that glucoascorbate augments the enzymic conversion of PGA to CF by liver tissue in vitro, while Welch et al. (16), administering glucoascorbate parenteral...
