Discriminant analysis (DA) encompasses procedures for classifying observations into groups (i.e., predictive discriminative analysis) and describing the relative importance of variables for distinguishing amongst groups (i.e., descriptive discriminative analysis). Discriminant function analysis showed that 91.96% of participants could be correctly classified as winners or losers on the basis of preperformance mood scores.

CONCLUSIONS: Although the HoNOS has many advantages in its brevity, it may lack sufficient discriminatory ability for certain patient groups. Conclusions: In children aged 8â12 years, analysis of ERP data may aid a clinician in diagnosing AD/HD, although the clinical utility of ERP analysis is reduced for adolescents aged 13â18 years.

Well, in the case of the two group example, there is a possibility of just one Discriminant function, and in the other cases, there can be more than one function in case of the Discriminant analysis. Discriminant function analysis (DFA) is a statistical procedure that classifies unknown individuals and the probability of their classification into a certain group (such as sex or ancestry group). In order to achieve that discriminant analysis is based on the estimation of the orthogonal discriminant functionsâ¦ Also, the motto of LDA is to model a discriminant function to classify.
