Dear all, 

When estimating a LogL function with -ml-, e.g.

program test
  version 9.1
  args lnf xb theta1
      qui replace `lnf' = ln(...) if $ML_y1 == 1
      qui replace `lnf' = ln(...) if $ML_y1 == 2

ml model lf test (y= ) / theta1
ml maximize

How does Stata know that -xb- corresponds to the first equation and
-theta1- to the second?

Should the order that the arguments appear in -args- be the same as the
order they appear in the LogL?

Thank you
