Statistics for Data Science and Business Analysis - Decomposing the Linear Regression Model - Understanding its Nuts and

This video tutorial explores the determinants of a good regression model using the ANOVA framework. It defines three key terms: Sum of Squares Total (SST), Sum of Squares Regression (SSR), and Sum of Squares Error (SSE). SST measures total variability, SSR indicates how well the model fits the data, and SSE represents the error. The video explains the mathematical relationship among these terms, emphasizing that lower error leads to a better regression model. The tutorial concludes with a preview of comparing different regression models in the next lesson.
