The task of this exercise is to predict the performance of students in a math course. Based on these predictions, students in need of additional support are assigned to private lessons. The files student-mat-train.Rdata and student-mat-test.Rdata contain data about student achievements from Portuguese schools. They contain information about the math grade, socio-economic characteristics of the students, and school related features. Table 1 contains the description of the variables (see https://archive.ics.uci.edu/ml/ datasets/Student+Performance for a more detailed data description).
