Module is not defined due to resolution errors

SASingaKorean — Mon, 06 Jul 2020 08:38:31 GMT

Hi, I am trying to make my own module but I have unexpected errors. The following is my module.

Proc iml;
Start op_fun (parm)
Global (start0, f, h ,a ,b, sigma_eta, sigma_e, y, rowz, rowy, coly, fix_f, fix_h, fix_a, fix_b, fix_sigma_eta, fix_sigma_e, pred, vpred, filt, vfilt);
Mu0 = &mu0.;
Sigma0= &sigma0.;
Run
Unpack_parm (f, h ,a ,b, sigma_eta, sigma_e, var, rowz, coly, fix_f, fix_h, fix_a, fix_b, fix_sigma_eta, fix_sigma_e, parm);
Call KALCVF (pred, vpred, filt, vfilt, y, 0, a, f, b, h, var, mu0, sigma0);
Et = y – pred*h`;
Const= 0.5 * coly * rowy * log ( 2* constant ('PI'));
Sum1=0;
Sum2=0;
Do i=1 to rowy;
Vpred_i = vpred [(i-1)*rowz+1: i*rowz,];
Ft=h*vpred_i*T(h) + var [rowz+1:rowz+coly, rowz+1:rowz+coly];
Neg_PED = const + 0.5 * (sum1 + sum2);
if (det(ft)<1E-8) then return (1E10);
et_i =et [i,];
sum1= sum1+log(det(ft));
sum2=sum2+et_i*inv(ft)*T(et_i);
end;
Return (neg_PED);
Finish op_fun;

However, I've got an error message saying that "Module OP_FUN was not defined due to resolution errors."

What is resolution errors? and how should I fix this problem? I am using SAS 9.4.

Moved to IML forum.

Please paste as code so the format is kept.

I moved the question to IML. You can delete my question here. Thank you

I moved it. No need to create a new one.

Please format your code 🙂

The "module not defined" error tends to occur when there is some mis-match of control statements. For example an "end" statement is not preceded by a "do" statement, or "else" is not preceded by "if". I don't actually see any such problem in the code that you have posted, so you may need to give more detail including the log with the full error message.

Invalid characters can cause syntax errors. For example, in the statement

Et = y – pred*h`;

the character that looks like a minus sign appears to be an "n dash", This can occur if you copy/paste the program from a PDF or RTF format.

If you change it to

Et = y - pred*h`;

it should resolve.

Thank you. Yes. You are right. I rewrote them and the problem solved. Thank you very much!
