The regression model forYieldas a function ofConcentrationis significant, but note that the line of fit appears to be tilted towards the outlier. We can see the effect of this outlier in the residual by predicted plot. The center line of zero does not appear to pass through the points...
Conditional Residual by Predicted Plot Shows the conditional residuals plotted against the conditional predicted values of Y. You typically want to see the conditional residual scattered randomly about zero. Conditional Residual Quantile Plot Shows the quantiles of the conditional residuals plotted against ...
