Little attention has been given to the behavior of option portfolio risk across different portfolio sizes, perhaps because many individuals view unhedged long option positions as too risky for rational investor consideration. It appears possible, however, to combine long option positions with less risky assets to produce portfolios with favorable risk-return characteristics [10].

Recently, a debate has developed in both the theoretical and applied statistical literature regarding the appropriateness of various techniques in analytical models with limited (particularly, 0-1) dependent variables. In financial research, limited dependent variable models usually arise in one of two ways:1. classification (or discrimination)--assigning observations to discrete, a priori determined groups, or2. regression--relating a qualitative dependent variable to one or more independent variables (which may or may not be qualitative).
