Research Questions Research question 1: When examined from a stepwise model for logistic regression, what is the relationship between the targeted variables and the dichotomous response variable that distinguishes between the presence and absence of the U.S. LCCs in the domestic routes? Research question 2: When examined the variable importance of the decision tree model, what are the most important factors that predict the presence or absence of the U.S. LCCs in the domestic routes? Research question 3: In the model comparison platform, between logistic regression and decision tree, which model performs more accurately in predicting the presence or absence of the U.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
