This data set can be used to demonstrate the differences between the model calibration and the prediction power.
The prediction power can be determined either with cross-validation or the application of the model to the data set cvq2.sample.A_pred
.
This data set contains one outlier (row #2). If the prediction power is determined with cross-validation, this outlier leads to a considerably decreased prediction power, q^2_cv, in comparison to the model calibration, r^2. For this data set, one can perform a Leave-One-Out cross-validation only.
Generic data set, created for this purpose only.
