why do variables fall backward in logistic regression which step in logistic regression would i do if all dummies on an indicator variable were eliminated? when do you backward select in r which variable is eliminated at variable selection based on aic? what is the difference between dummies and indicators in logistic regression which is a backward selection in logistic regression based on dummies how to remove dummies from glm what is the purpose of a single dummy in logistic regression? which is best to remove indicator variables from the regression r when does the dummy variable selection occur when the dummy is eliminated why do you discard dummies in r when selecting dummies what is glm indicator selection aic in logistic regression what is the purpose of backward elimination can i remove dummies when selecting a variable why is it important for variables in logistic regression to be discarded how to eliminate dummy variables in logistic regression what is the difference between glm and indicators in logistic regression why are indicators used in logistic regression is dummies removable during variable selection in logistic regression?
