setting reference levels for variables in proc surveylogistic

[joachimg]

Okay first of all.....if you saw my last post, no you didn't. ANYWAYS.....

I'm trying to run a logistic regression with proc surveylogistic and I'm having trouble setting my reference levels for the different variables. Here is my code:

proc surveylogistic data=masks1;
weight wt_multi;
class d_age_cat2 (ref=”0”) d_gender (ref=”MALE”) d_race (ref=”NH White”) d_politics (ref=”DEM“) d_religion2 (ref=”NOTHING”) vaxxed (ref=”0”);
model b2_m_always (descending) = d_age_cat2 d_gender d_race d_politics d_religion2 vaxxed;
run;

And here is the error message I get:

103        
 104        proc surveylogistic data=masks1;
 105        weight wt_multi;
 106        class d_age_cat2 (ref=”0”) d_gender (ref=”MALE”) d_race (ref=”NH White”) d_politics (ref=”DEM“)

Please help! Proc surveylogistic has been killing me lately. Thanks in advance.

Did you copy and paste that from
somewhere? The quotation marks appear a bit messed up - try retyping the code and make sure to use the formatted reference values. Also, put the weight statement after the CLASS statement.

I suspect the only issue is the quotation marks being messed up though.

You know, I knew it was gonna be something dumb like that. Thanks!

Can I ask why move the weight statement? Seems to be working fine, and that's how my PI had me do it. Just curious.

I’m in the habit of putting them in the order as it shows in the docs. There’s a few good reasons for this - makes it easier to read your code and if you use patterns for coding updates and fixes are easier. Following the doc order is something most SAS programmers do so its a good way to have consistent clean code. For some procs/statements the order does matter as well, and I can never remember which ones so defaulting to keeping them in order works in general.
