Array and Where statement in proc nlmixed

[issac]

Hi everyone;

Am working with 9.3 version. I just wonder if we could use where and array statements in proc nlmixed and if that's possible where to put them?

Thanks!

The ARRAY statement is documented in the manual.  Note that it is different than the ARRAY statement in a data step.

What do you want the WHERE statement to do?  For most procedures that simply subset the data being read from the input dataset.

I would normally place it immediately after the PROC statement, but in many procedures it does not matter where it is placed. 

proc nlmixed data=mydata ... ;

where id > 1000 ;

...

run;

You can also code a WHERE condition using a data set option on the input file.

proc nlmixed data=mydata(where=(id > 1000)) ... ;

...

run;

By ARRAY I want to do some programming in the body of proc nlmixed, but I guess if I can do it in the data step, it cost much less time since it needs to be done one time. So I go better off switch to data step.

Also by means of WHERE I exactly want sub setting of data set being processed by nlmixed and not sure where to put it. But now I know.

Thanks so much Tom;
