I am looking to evaluate if the change in proportion for a group changed pre-to-post intervention.
Essentially, is the ~7% increase from pre (~2%) to post (~9%) significant. I am running the McNemar test in SAS 9.3 as follow:
ODS HTML CLOSE; ODS HTML; PROC FREQ DATA = AGE0_10_SUM ORDER = DATA; WEIGHT MEMCOUNT; TABLES AGE0_10*SRC / AGREE; TITLE "AGE0_10"; RUN; ;QUIT;
This is resulting in a p-value less than 0.0001. I think the change is significant but not at this magnitude, also, when running other age groups the results for a 0.02% increase was also <0.0001. Something is wrong.
How should the table be set-up to run the McNemar test with AGE0_10 as being the repeated subject pre and post.
