This data set can be used to determine the prediction power of the model M generated with
The four observations y depend on two parameters (x_1, x_2).
A data frame with four observations. Each row contains two parameters and the observed value.
This data set fits very good to the model M derived from
The prediction power q^2 of M for
cvq2.sample.A_pred is as high as its calibration power, r^2.
Generic data set, created for this purpose only.
