What are the Limitations of Linear Regression in Epidemiology?
While linear regression is a powerful tool, it has limitations: 1. Linearity Assumption: Not all relationships are linear. 2. Influence of Outliers: Outliers can disproportionately affect the model. 3. Multicollinearity: Highly correlated independent variables can distort the results. 4. Causality: Linear regression shows association but not causation.
