Nettet3. In the 2-group situation, the cut-off value of the discriminant function scores is simply the mean of the means of the scores for the groups (those means are also called "function's values at group centroids"). Say, if for group 1 the mean score is -.742 and for group 2 it is .576, then the cut-value for classifying is their average, -.083. NettetPrediction Using Discriminant Analysis Models. predict uses three quantities to classify observations: posterior probability, prior probability, and cost. predict classifies so as to …

NettetLinear Discriminant Analysis. LDA computes “discriminant scores” for each observation to classify what response variable class it is in (i.e. default or not default). These scores are obtained by finding linear combinations of the independent variables. For a single predictor variable X = x X = x the LDA classifier is estimated as. ^δk(x ... harlem lyrics
