Multiple Discriminant Analysis (MDA)    
     
Classification Matrix - Sample
statistical modelling | multiple discriminant analysis (3-step analysis | step-2) | cluster analysis (research design issues)

2-Group Dependent Variable (A and B)
   Predicted Group Membership    
 Actual  A  Actual Total Percent number correctly classified by group
 Xa  Yb Xa +Yb Xa / (Xa + Yb) 
B  Ya  Xb Ya + Xb  Xb / (Ya + Xb) 
 Predicted Total Xa + Ya  Xb + Yb     
 
         
 Variable Name  Explanation
 Xa The actual number of observations in Group A
 Xb The actual number of observations in Group B
 Ya The number of observations wrongly classified by the discriminant function in Group A
 Yb The number of observations wrongly classifed by the discriminant function in Group B
 
The hit - ratio for the above 2-group classification matrix is [(Xa + Xb) / (Xa + Xb + Ya + Yb)] · 100
