I have two questions concerning the market simulations with aggregate logit.
First of all, I would like to know if there is way to calculate hold out hit rates. I was just able to analyse the MAE with CBC/logit using SMRT. Moreover, I would like to do sensitivity analysis using my utilities from CBC/logit. I used share of preference (I have an alternative specific design) and in my outputs I can not find any standard error, since I need this to have certainty about significant differences in market shares by changing levels of attributes.
Thank you for your support.
