Episode 10 — Make sense of regression outputs: coefficients, residuals, significance, and fit
This episode teaches you how to read regression output like an analyst instead of treating it as a wall of numbers, which is a core DY0-001 skill for both modeling and evaluation questions. You will interpret coefficients in context, including how units and scaling affect meaning, and you’ll learn why sign and magnitude matter only when the model assumptions and feature design make sense. We’ll cover residuals as the diagnostic heartbeat of regression, showing how patterns can reveal missing variables, nonlinearity, heteroscedasticity, and outliers that distort fit. You’ll also learn how to handle statistical significance responsibly, including the difference between “statistically detectable” and “useful,” and how multicollinearity can make coefficients unstable even when overall fit looks strong. We’ll close by connecting fit measures to decision-making, emphasizing when regression is appropriate, when it is misleading, and what to troubleshoot before you trust the output.
