how to add media channel without spend variable about robyn

[gufengzhou]

Hey, thanks for flagging this. Well this is a tricky one. Robyn does not have the feature yet to deal with variables without spend but requires transformation. For now, the recommendation is just put them as baseline variables. You can maybe try to do adstocking manually and then put them as baseline variable. We'll put this on the wish list

Hey, thanks for the reply.
Make sense. I'll try to add it as a baseline variable with manual adstocking for the time being
Thank you!

Hi,

This would be an awesome feature. How would I calculate the decay manually for these variables? There’s obviously 0 saturation effect.

Would I need to estimate a decay rate manually and then perform the transformation on the variables of interest? @gufengzhou
