Dear All,
I would really appreciate some help on this small problem about elasticities of QUAIDS. I am trying to obtain QUAIDS elasticities after running Poi(2012) program to estimate a 5-good demand system with 4 demographics characteristics. Running the following commands to estimate a QUAIDS model in Stata 13.1:
I obtain the following results of elasticities:
However, the results of QUAIDS parameters are quite good
Thank you for any suggestion and advices
Kind regards
David
