Hi
I have a bit of a weird problem:
I constructed a project in model studio in Viya, and used event-based sampling. The different models all had Roc/accuracy curves that looked something like this:
Great, that is what I expected.
Now I had some issues with modelmanager, and I had to reconstruct the project. Using the same dataset, the same models and again using event-based sampling, the curves now looked like this:
The probabilites were now around 95 % for an event=1, whick was in accordance with the distribution in the original dataset but NOT what i would expect after having done evet-based-sampling.
Obviously I must have done something different in the second project...But any ideas of WHAT box I might have ticked or what I might have otherwise done, that can cause this difference, would be much appreciated
thx
