This project presents a multiple linear regression analysis using the Ordinary Least Squares (OLS) method in R. The study examines the impact of study hours and attendance rate on student exam scores. The analysis includes manual matrix-based estimation, hypothesis testing (F-test and t-test), coefficient of determination (R-square and Adjusted R-square), model validation using the function in R, and prediction.
