bootstrapped skill scores on denormalised data
Currently normalised forecasts are only stored for the purpose to be usable for the bootstrap analysis. But this could be also performed in the original value space if the retransformation is applied to the bootstrapped prediction. Maybe it is worth to save the computation time of normalised forecasts and apply transformation on the bootstrap predictions instead.
Before taking a decision, first check if the norm forecast is only used by the bootstrap methods or somewhere else.
