Factorial Variables #806

Closed mirgolian closed 10 months ago

mirgolian commented 10 months ago

Hi, I would like to ask what is the correct interpretation of factorial variables used in Robyn? When I look at the waterfall graph, do I compare its effect with average category, or with a default one. If the latter is correct, how do I find out which one has been set as the default, and possibly change it? And lastly, when I have more than one category, where can I find effect of each of them? Thanks!
