Hi Racha,
I was trying to write stata coding for estimating dynamic quadratic almost
ideal demand model and got the same kinds of error messages for a couples
of times. I corrected my coding error using "set trace on" command on
stata. What
you need to do is the following. First write a command "set trace on" and then
run you do file, the stata will stop executing at the point you make a
mistake. Then correct you mistake until the programe will execute the
result.
I hope this will help.
Best
Nigussie
