question about where statement within Proc Logist

Hello,

 

I'm using SAS 9.4 full version. Is there a place in the following proc logist coding to put a where statement?  I'd like to run this regression only when a binary variable CASE='1'.  

 

Thanks

Laura

 

proc logist descending; 

class VARIABLE1 VARIABLE2 VARIABLE3; 

model Payment=VARIABLE1 VARIABLE2 VARIABLE3 VARIABLE4 / rsquare; 

run;

proc logistic?

 

You can specify a WHERE statement most anywhere;

 

proc ...;

where case eq '1';

... more statements ...

run;

 

I usually use the data set option.

 

proc logistic data=sashelp.class(where=(age le 15));
  class sex;
  model sex = height weight;
run;

Re: question about where statement within Proc Logist

Did you try

proc logist descending; 
   where case='1';
   class VARIABLE1 VARIABLE2 VARIABLE3; 
   model Payment=VARIABLE1 VARIABLE2 VARIABLE3 VARIABLE4 / rsquare; 

run;

It is a very good habit to always use the data= on the proc statement.

 

If you are working with multiple data sets with the same variables as in the modeling code there is a chance that you might just accidentally run this against the wrong data set if you run blocks of code manually.

 

Any chance that should be LOGISTIC?

if that doesn't work then this should

proc logist descending data=_last_(where= ( case='1') );

 @lmyers2 Make sure to look up how CLASS variables are handled, the default encoding is GLM which is unlikely what you want.
