The third method used of discriminatory analysis to retain items which could distinguish between men with BPH and men without BPH.
Since there was the need to use objective methods to get more credible results[ 13], we used scoring by experts, coefficient of variation, discriminatory analysis, multiple regression, Cronbach'α coefficient, coefficient of correlation, factor analysis, and cluster analysis to objectively select items that were representative enough to assess the quality of life of BPH patients[ 2, 9, 12, 13].
Due to this, the findings of discriminatory analysis need to be interpreted with caution.
Discriminatory analysis, carried out with the help of a computer, allowed all of these variables to be assessed with respect to each other in order to arrive at a numerical score for each specimen.
A descriptive discriminatory analysis (DDA) determined whether a combination of the preparatory and propulsive PC scores could be used to discriminate among the three locomotor modes [e.g.], [ 29], [30,31].
Once confirmed, Tukey's B discriminatory analysis was performed to determine the existence of significance differences between the groups.
A statistical classification model was also designed using linear discriminatory analysis and support vector machines which permitted the differentiation of the flint on an age basis.
Subsequently, discriminatory analysis and ROC curves were used to establish and assess predictive diagnostic models of CAP by using these four independent factors.
Univariate analysis, multivariate analysis, discriminatory analysis and Receiver Operating Characteristic (ROC) curves were used to build predictive models for etiological diagnosis of adult CAP.
