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

Roger

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
