plot_residual_qq(y_true: ndarray, y_pred: ndarray, *, title: str = 'Normal Q-Q of residuals')

Quantile-quantile plot of the residuals against a normal reference.

Residuals lying on the reference line are consistent with the normality that many regression inferential procedures assume; systematic S-curves or heavy tails flag a violation.

Parameters:

• y_true – Observed responses.

• y_pred – Predicted responses.

• title – Figure title (sanitised).

Returns:

The matplotlib Figure.
