You are getting this error because you are breaking the line at the wrong place. Your code should be:
ivreg D.s2 (D.lp23 D.lp13 L.D.s2=L(2/3).s2 D(0/1).(a b c)) D(1).(x y z), noconst
parmest, saving(eq2, replace)
This is because -parmest- is a separate command to -ivreg-, and therefore should be on a different line.
Or, alternatively, if you have the delimiter set to a semicolon, your code should be:
ivreg D.s2 (D.lp23 D.lp13 L.D.s2=L(2/3).s2 D(0/1).(a b c)) D(1).(x y z), noconst;
parmest, saving(eq2, replace);
I hope this helps.
Best wishes

Hi all,
I am getting the following error message when I run a portion of code:
. noconst parmest, saving(eq2, replace)
unrecognized command: noconst
r(199);
Code below:
ivreg D.s2 (D.lp23 D.lp13 L.D.s2=L(2/3).s2 D(0/1).(a b c)) D(1).(x y z),
noconst parmest, saving(eq2, replace)
Any idea why this command is unrecognized?
Thank you in advance
