The Feature Pattern Analysis (FPA), as introduced by Feger (1988), is a method which analyzes a set of observed patterns with respect to co-occurrence. The mathematical formalism of the FPA and the several logically equivalent alternative forms of its representation as geometrical configurations, sets of contingencies and sets of prediction rules are described. Mathematical conditions for the uniqueness and existence of Type I and Type II FPA-solutions are discussed. A fast algorithm is developed to construct a two dimensional FPA-solution using Hasse-diagrams. |
