Dear Marcel,
Hard to see the problem.
(1) change line mleval `I2' = `b' eq(2)
for mleval `I2' = `b', eq(2)
(2) do you have an open dataset when you type
-ml check-?
(3) if you type -set trace- after -ml model- and run it
you will see every step in the process.
Good luck, Rodrigo.

Subject: st: ML estimation
Dear stata-users,
I want to estimate by ML a model with two equations. The structure of the
program is as follows:
program define hshazll2
version 8.2
args todo b lnf
tempvar I1 I2 h1 h2 sum1 sum2 ST1 ST2 last lnfi
mleval `I1' = `b'
mleval `I2' = `b' eq(2)
....
....
....
end
When I call the program with the following line:
ml model d0 hshazll (I1: y1 = x1 x2) (I2: y2 = x3 x4)
and continue with a check:
ml check
I get the message "no varlist allowed"
In the MLE book by Gould I find similar examples that seem to work. What is
wrong here?
Regards,
Marcel Spijkerman
