fairlie decomposition

MSALKAR — Fri, 03 Mar 2017 22:38:28 GMT

Hello, I keep getting these two error messages when I run my simulation. I cannot figure out where the error is. I am just posting some part of my code where I feel there may be an error. I know the data looks long but it is pretty much just same line with different numbers. So please go through. If required I will post the complete code. Thank you.

Next time please post the log.

It looks like one of the data set does not have any numerical variables. The error is probably one of these line:

use monika.covar;
read all var _num_ into V;
use monika.cont1;
read all var _num_ into DC1DB;
use monika.cont2;
read all var _num_ into DC2DB;
use monika.cont3;
read all var _num_ into DC3DB;
use monika.cont4;
read all var _num_ into DC4DB;
use monika.cont5;
read all var _num_ into DC5DB;
use monika.cont6;
read all var _num_ into DC6DB;

This is the error I can see in my log. I am still not understanding where the error is. Let me know what else you need inroder to help me fix this problem. Thank you

ERROR: (execution) Matrix has not been set to a value.

I see that there is a problem with these lines

use monika.covar;
read all var _num_ into V;
use monika.cont1;
read all var _num_ into DC1DB;
use monika.cont2;
read all var _num_ into DC2DB;
use monika.cont3;
read all var _num_ into DC3DB;
use monika.cont4;
read all var _num_ into DC4DB;
use monika.cont5;
read all var _num_ into DC5DB;
use monika.cont6;
read all var _num_ into DC6DB;

My log states that all of the above datasets do not have numeric variables.
Is there a way to code the above same code for categorical variables?
Please let me know.
