I did a log transformation on my observed variables before entering them into my model. Now I would like to take the exponential of them so that when I do things like have an az.plot_ppc plot in original variable rather than its log transformation. Any advice on how I can do that or if I even can?

You can use InferenceData.map to apply the same transformation to both observed_data and posterior predictive (and or to prior predictive too) which are the quantities used in plot_ppc. This is the first example in arviz.InferenceData.map — ArviZ 0.14.0 documentation . Let me know if you have any iss…

I have found one more question. Do I have to make any changes if I take the exponent of my data? I seem to get a blank page once I map np.exp to it.
