R Programming for Statistics and Data Science - Decomposition of Variability: SST, SSR, SSE

This video tutorial explores the determinants of a good regression model using the ANOVA framework. It explains the concepts of Sum of Squares Total (SST), Sum of Squares Regression (SSR), and Sum of Squares Error (SSE), highlighting their roles in measuring variability and model accuracy. The video also discusses the mathematical relationship among these terms, emphasizing the importance of minimizing error for better regression estimation.
