how to find out association between two variables by using proc logistic

chinna0369 — Thu, 06 Feb 2020 23:02:35 GMT

Hello all,

My data looks like below:

id hdl_hi age_hi
2 1 1
3 0 1
4 0 1
5 1 1
6 0 1
7 1 1
8 0 1
9 0 1
11 1 1
12 1 1

I am trying below code to find out association between hdl and age. Could you please confirm that is this correct procedure? and where to look for association details?

proc logistic data=step1;
class age_hi(param=ref ref="1");
model hdl_hi (event="1")=age_hi;
ods output fitstatistics=log2ratio_full
globaltests=df_full;
run;

Below are the stats produced from my code:

Any help would be appreciated.

Thanks,

Adithya

Usually, I understand the word association to mean a contingency table, such as would be produced by PROC FREQ.

Example: https://documentation.sas.com/?docsetId=statug&docsetVersion=15.1&docsetTarget=statug_freq_examples05.htm&locale=en

In your simple case with 2 levels of each variable, this may be the same as your PROC LOGISTIC code, I don't remember the exact math anymore.
