Hi there,
I am not sure if this is right place to request additional features. If not, please point me a right place.
Now ModelConfig is nicely handling parameters for parameter of interest, nuisance parameters and global parameters, but entirely misses another category: normalization factors. Many analyses are introducing unconstrained normalization factors to scale the number of background events and perform the fitting to obtained these normalization factors. But these factors are not the parameter of interest nor being constrained.
I propose in the ModelConfig to add a category to label normalization factors so that they could be treated differently.
