Before: Heteroscedasticity, wherein the variance of residuals is non-constant across levels of the predictor, violates the homoscedasticity assumption of ordinary least squares.
- Residuals are the gaps between predictions and reality.
- Heteroscedasticity: those gaps change size as the predictor grows.
- Ordinary least squares assumes the gaps stay the same size.
