How regression performance varies with noise

Here's a table showing how the various performance measures from the regression performance operator change as more and more noise is added for a regression problem (it's the process referenced in another post).

This is not a feature of RapidMiner as such, it's simply a quick reference to show the limits of these performance measures under noise free and noisy conditions so that when they are seen for a real problem, the table might help orientate how good the model is.
