Goodness of fit/ model accuracy

[eeghor]

@JulianZeissler Do you know the correct contributions by each touchpoint? If you do, using AIC may make sense, why not. Or you could just calculate some accuracy that looks reasonable to you.

If you don't know the correct contributions, I'm afraid there's no way to pick the "best" model. All you can do is decide which model seems well aligned with your use case by design, i.e. based on how it works. For example, you may have serious doubts that let's say a Linear model is a good choice for your campaign just because you really don't believe that all touchpoints can contribute equally. Then you don't go with the Linear model and consider something different instead.
