Dear Statalisters, I'm using the 'aidsills' command for estimating demand systems developed by Lecoq and Robin [Full reference: Lecocq, S., and Robin, J.-M. (2015). Estimating almost-ideal demand systems with endogenous regressors. The Stata Journal 15, 554-573]. I want to calculate price and income elasticities for indivudal cases or observations.
I would be happy if anyone has experience or ideas to share with me.

Thank you.
