In this paper some of the common misuses of discriminant analysis are discussed. The problems fall into four groups:

1. Study goals are unfocused;

2. improper sampling procedure;

3. assumptions are violated;

4. variables are poorly defined or selected.

Identification of these problems leads to the appropriate corrective action.

In dieser Arbeit werden einige der üblichen Mißbrauche der Diskriminanzanalyse erörtert. Die Probleme können in vier Gruppen eingeteilt werden:

1. Die Zielsetzungen der Studie sind unscharf formuliert;

2. ungeeignete Stichprobenverfahren;

3. Annahmen bleiben unbeachtet;

4. Variable werden schlecht definiert oder ausgewählt.

Die Identifikation dieser Probleme fuhrt zu entsprechenden Verbesserungen.
