This means that what is group 1 in the K = 2 facet may be very similar to group 4 in the K = 3 facet. For example, group 2 at K = 4 appears to be group 5 at K = 5. At the present I handle this with a manual step, which I’ve omitted here.It is frequently preferred over discriminant function analysis because of its less restrictive assumptions. # Logistic Regression # where F is a binary factor and # x1-x3 are continuous predictors fit <- glm(F~x1+x2+x3,data=mydata,family=binomial()) summary(fit) # display results confint(fit) # 95% CI for the coefficients This analysis was performed by univariate analyses of variance using a critical value of α = .008 in light of the comparison of the total score and 5 indexes.
