proc freq binomial level=1

ashleyazar — Tue, 20 Oct 2015 19:48:25 GMT

Hi,

I have a response variable codes as 1="Respnse" and 0 ="Non-Response". If i use level=0, i get an error stating that the level should be a positive integer. How do i get the proportion of non-responders?

%if %str(&tabnum)=%str(1049.1.1) /*or %str(&tabnum)=%str(1049.1.2)*/ or %str(&tabnum)=%str(1049.1.5) %then %do;

proc freq data=dsin;

BY &byvar viswin efques leg_sort;

tables &value / binomial (level=1);

where not missing(remiss);

exact binomial;

ods output OneWayFreqs=freqs BinomialProp=ExactBiCI(where=(name1 in("XL_BIN", "XU_BIN")));

run;

%end;

%else %do;

The LEVEL= option refers to the variable level (or order), not to the actual value itself. If you use LEVEL=1, it will give you the proportion of Non-responders (=0). Compare it to LEVEL=2, which should give the number of responders (=1).

Hi,

you can just use

level="1" even if it is numerical.

In this way it works.
