This monograph is intended as a practical guide to business applications of the theory of discrimination information statistics as developed by Kullback (1959) and Charnes and Cooper (1975 et seq.). A guide to modeling and computation methods is presented, with references to published applications and a discussion of their implications for business and planning. These implications are developed by means of detailed examples showing MDI to be a practically workable unifying principle for the analysis of demand and market structure. Some applications in other management areas are also noted.
