Sorry, I am a little confused. Two expressions:
(1) replace `lnc'=`a'*`lnpe'+`b'*``lnpe'*`lnpe''
(2) replace `lnc'=`a'*`lnpe'+`b'*`lnpe'*`lnpe'
Which is the correct one?

Quoting Nick Cox <[email protected]>:
``lnpe' or `lne'' can not be legal. As in ordinary language, single
quotes must be in matching pairs.

First, I corrected all the typo.
Then I changed constant item 5 to a0 in the first equation. I setted
constant item a0 as a strating value 5 in my previous codes, because
they did so in the example. Now I decide to scalar a new coef. a0. Is
that ok? Or I need to set the constant item at other starting value?
Second, I typed -set trace on- before running the stuff. Here's the
error record:
}
-------------------------------------------------------------- end
nlsurwellbehav ---
- }
- if _rc {
- di as error "nlsur`eqn' returned " _rc
= di as error "nlsurwellbehav returned " _rc
nlsurwellbehav returned 111
- di as error "verify that nlsur`eqn' is a function evaluator program"
= di as error "verify that nlsurwellbehav is a function evaluator program"
verify that nlsurwellbehav is a function evaluator program
- exit _rc
}
}
---------------------------------------------------------------- end
nlsur.Estimate ---
end nlsur ---
r(111);
I am thinking there maybe another kind of errors in my codes. Say
there's two items in my equation: a*lne and b*lne*lne. I think I
should define them as:
replace `lnc'=`a'*`lne'+`b'*``lnpe'*`lne''
In my previous codes I defined them as:
`lnc'=`a'*`lne'+`b'*`lnpe'*`lne'
Does it cause the r(111)?
