Greetings, dear Statalist members!
Could I use Stata to estimate a one-stage stochastic frontier with exponential, log-normal and half-normal distributions?
I run the command below using Stata:
sfcross lny lnland lnlabour lnfertilizer lnseed, dist(hn) 0rt(o) emean (age sex education extension credit)
But I got the error message "Conditional mean model is only allowed for distribution(tnormal)".
I kindly ask you to share the commands with me.
Thank you in advance for sharing your busy schedule with me.
