Hi, I have a few questions about the estimation of the QUAIDS model (the program by Brian Poi). They may sound trivial but any help will be greatly appreciated! - I was wondering if one needs to normalize prices to estimate the elasticites. I am using a cross-sectional survey, so I can not compute a price index over time but I can normalize using the regional variation. - Is it possible to incorporate demand shifters in this model? I included two dummy variables and household size under the nlsur command but is it appropriate? - Is there a way to recover the standard errors of the elasticities? Many thanks in advance! * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
