From an estimateGraph object and a corresponding data set, candidate treshold values are compared on the prediction performance of the corresponding additive Kriging model. The candidate thresholds are chosen by the biggest jumps in plotDeltaJumps together with 0 (the full model) and 1 (the complete additive model). For each of them the Kriging model with corresponding kernel is estimated and the leave-one-out crossvalidiations on the original data sets are compared on scatterplots and RMSE-values.

Estimates the structure of the FANOVA graph by estimating the total interaction indices for the graph edges (a particular case of superset importance introduced by Liu and Owen, 2006), the main effect indices for the graph vertices and the overall variance for normalizing the indices and finding the clique structure of the estimated graph.

Threshold discision plot. plotDeltaJumps plots the threshold steps (the values of delta at which the graph changes) equidistant against the number of cliques and the values of delta on the real axis. The indices are assumed to be scaled for the threshold cuts.
