Stepwise discriminant function analysis for rapid identification of acute promyelocytic leukemia from acute myeloid leukemia with multiparameter flow cytometry. REQUIREMENTS: Discriminant analysis tests n predictor (independent) variables as discriminators of the differences between k groups of a single discrete (categorical) dependent variable. DFA (also known as Discriminant Analysis--DA) is used to classify cases into two categories. DISCRIMINANT FUNCTION ANALYSIS (DFA): Is used to model the value (exclusive group membership) of a either a dichotomous or a nominal dependent variable (outcome) based on its relationship with one or more continuous scaled independent variables (predictors). The results feed into the second goal of this paper, which is to show that a “South Asian” craniometric identity can be discerned at the level of the individual cranium, as well as the population level (as previously demonstrated by Raghavan et al.

The triple-negative (CD34-/HLA-DR-/CD11b-) profile rapidly and specifically identifies an acute promyelocytic leukemia. The analysis creates a discriminant function which is a linear combination of the weightings and scores on these variables. as possible in order to learn which one(s) offer the best prediction. High values of the average come from one group, low values of the average come from another group. -, Cytometry. The weights are selected so that the resulting weighted average separates the observations into the groups. 2000 Apr 15;42(2):106-9 Fifty samples (10 samples of each body fluid) were used as a validation set to examine the accuracy of the model, and 25 samples (the types of samples were unknown to the experimenter) … features of discriminant analysis in classifying three, “LOW (2)”, “MOD (3) ”, and “HIGH (1)” price groups. However, diagnostic interpretation of MFC readouts for APL depends on individual experience and knowledge, which inevitably increases the risk of arbitrariness. Save for later. Find books Immunophenotype distinction between acute promyelocytic leukaemia and CD15- CD34- HLA-DR- acute myeloid leukaemia with nucleophosmin mutations. NLM 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.
