Hi,
I am trying to estimate a 4 goods QUAIDS model that corrects the problem of censoring in the dependent variable (zero expenditure problem) using the Shonkwiler and Yen method (1999): Shonkwiler, J. Scott, and Steven T. Yen. "Two-step estimation of a censored system of equations." American Journal of Agricultural Economics 81.4 (1999): 972-982.
After that, I will extend the analysis to 20 goods. I am using the “nlsur” command to estimate the QUAIDS model with Shonkwiler and Yeh method. I am a beginner in programming with Stata, so if someone could share the code to calculate the elasticities (price, expenditure, uncompensated and for demographics components) or give some tips I would really appreciate some help on this.
