Joint Modeling of Exam Results and Attrition Status of Students at Hawassa College of Education, Ethiopia

Abstract

Student attrition is a challenge for higher education institutions across the world. The purpose of this study was to examine the application of joint model using students' commutative grade point average and attrition status. A total of 258 college student samples were used in this study. A mixed effect model for students' grade point average and a Cox hazard model for students' attrition status were modeled independently, and both submodels were modeled jointly by linking random effects through a shared parameter model. This study focused on gender issues, academic background, peer support, and residence. From the finding of this study, 26.4% were attrition, and 73.6% were retained. The estimated trend of commutative grade point average was found to be negatively associated with attrition status. The major factors that encounter students' attritions were academic background and institutional factors.
