Hey,
Variables are effects coded in Lighthouse studio when it comes to Logit analysis.
Assuming this, I have two questions:
1) which level is taken as the reference level? E.g. there is an attribute with 7 levels (1,2,3,4,5,6,7). Does Sawtooth Lightouse Studio take the first (1), or last (7), or another one? (and which and why).
2) If the attributes are already effect coded due to the development process of the design file with NGENE and e.g. Level 1 (of 7) was defined as reference level, does Lighthouse studio consider this, or is this effects coding not relevant any more for the further process of analyzing in Sawtooth?
Thanks a lot for your help. I searched the forum (and the help) but didn't find a satisfactory answer.
kind regards,
Boris
