The primary objective of this research project is to increase freshman retention at the Ira A. Fulton Schools of Engineering. The research team will endeavor to analyze and refine the linear regression models created by Arafat and Pedroza in the spring of 2018. The models are designed to identify freshman students who have a high probability of leaving the Ira A. Fulton Schools of Engineering. This will enable the ASU advising department to focus their efforts to retain these students. In addition to analyzing the existing models, the team will also investigate by creating non-linear models for identifying at-risk students.
