PRIMA, a new supervised classification method is based on the concept of class distance (Euclidean distance). For each class, a separate class distance is defined on the basis of the centre of gravity and inhomogeneity for the class; this class distance is then used to produce the classification. The PRIMA classifier based on class distance can be applied in different, complex cases. The conditions of applicability are less strict than those of other methods. The algorithm is simple; efficiency and stability are good. The simplicity of the method even for complex cases, e.g., with very many variables or multicategory classification, or with noisy or incomplete data processing, is noteworthy when compared with other effective pattern recognition methods.
