plotD3_rec | R Documentation |
Error Characteristic curves are a generalization of ROC curves. On the x axis of the plot there is an error tolerance and on the y axis there is a percentage of observations predicted within the given tolerance.
plotD3_rec(object, ..., scale_plot = FALSE)
plotD3REC(object, ..., scale_plot = FALSE)
object |
An object of class 'auditor_model_residual' created with |
... |
Other 'auditor_model_residual' objects to be plotted together. |
scale_plot |
Logical, indicates whenever the plot should scale with height. By default it's FALSE. |
REC curve estimates the Cumulative Distribution Function (CDF) of the error
Area Over the REC Curve (REC) is a biased estimate of the expected error
