Statistics for Data Science and Business Analysis - A5. No Multicollinearity

The video tutorial explains multicollinearity, a statistical phenomenon where two or more variables in a regression model are highly correlated, leading to inaccurate coefficient estimates. It provides examples, including a real-life scenario involving bar prices, to illustrate the concept. The tutorial discusses the impact of multicollinearity on regression results and offers solutions such as dropping variables, transforming them, or handling them with caution. It emphasizes the importance of checking correlations between variables before running a regression model.
