Steps in Discriminant Analysis Fourth Step  “Standardized canonical discriminant function coefficients” table is used to find the relative importance of the variables in the model. In general, STATISTICA continues to choose variables to be included in the model, as long as the respective F values for those variables are larger than the user-specified F to enter; STATISTICA excludes (removes) variables from the model if their significance is less than the user-specified F to remove. Epub 2016 Jan 12. However, diagnostic interpretation of MFC readouts for APL depends on individual experience and knowledge, which inevitably increases the risk of arbitrariness. Please enable it to take advantage of the complete set of features! Finally, additional 20 samples from patients with atypical APL and AML confusable with APL were also identified by SDFA method and morphological analysis. NCI CPTC Antibody Characterization Program, Cytometry. When you have a lot of predictors, the stepwise method can be useful by automatically selecting the "best" variables to use in the model. The sexing function manifested both size and shape elements. 2000 Apr 15;42(2):106-9 The director ofHuman Resources wants to know if these three job classifications appeal to different personalitytypes. In fact, if classification is the ultimate goal, we need only estimate the class density well near the decision boundary[Hastie et al., 2001]. A separate set of classification function coefficients is obtained for each group, and a case is assigned to the group for which it has the largest discriminant score (classification function value).
