The plot shows RMSE values obtained at each iteration of the iPLS 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.
