Hi @nperez,
In this MR I am adding the Crossval_multimodel_metrics.R script with an adjustment so that it also works for the single-model case, and to include the development for the rps + rpss for the different probability categories. However, I am not replacing the original single-model Crossval_metrics.R script yet, because I have noticed some differences between the two scripts that I would like to discuss with you first.
I will make a list of the things I have noticed; we could talk about them on Monday or schedule a separate meeting if needed.
