Promotional spend

[Rolandas-LM]

Greetings,

I have two specific variables: coupon spend and some kind of specific promotional spend. In our company operations these two behave in a similar way as regular(TV, radio, FB, etc) spend and are included in our marketing budget. I would like to include them in the model and budget allocator. My questions and concerns are :
a) what hyperparameter ranges should I use? Should I treat them more as TV or digital?
b) I would like to remove saturation curve for one of these. How can I achieve that?
c) how can I edit one-pager and dimensions of the charts? My variables do not fit in those and one-pager is not presentable.
