All plots involve cross-validated predictions and/or cross-validated standardized residuals. The cross-validation is in the sense that for predictions made at design point x, all observations at design point x are removed from the training set.
Where relevant, open circles correspond to Gaussian process predictions, black lines correspond to the observations, and red lines correspond to confidence bands. The argument type
determines the type of graph displayed, and is one of the following integers:
|
0 for observed vs. predicted AND observed vs. standardized residual (default), |
|
1 for observed vs. predicted only, |
|
2 for parameter vs. predicted for all parameters, |
|
3 for parameter vs. standardized residual for all parameters, |
