The plot shows RMSE values obtained at each iteration of the iPLS selection algorithm as bars. The first bar correspond to the global model with all variables included, second - to the model obtained at the first iteration and so on. Number at the bottom of each bar corresponds to the interval included or excluded at the particular iteration. The selected intervals are shown with green color.
