Hi! I'm wondering if there is an option to include in the Proc Logistic preocedure that would output the number of observations used for each variable?
for example, if i am using gender as an independent variable, can I add something to the procedure that would output # males and # female observations in addition to all the statistical output?
Thanks!
You will easily get some useful information (means, frequencies) in proc logistic with option SIMPLE.
proc logistic data=sashelp.heart simple;
class sex smoking_status;
model status = sex smoking_status weight;
run;
every table can be captured with ODS OUTPUT.
Not AFAIK, in general, I run a proc freq/means ahead of time to get a table of characteristics.
Here's one way to get several proc freq results into a nice table at once:
https://gist.github.com/statgeek/e0903d269d4a71316a4e
/*This code is an example of how to generate a table with
Variable Name, Variable Value, Frequency, Percent, Cumulative Freq and Cum Pct
No macro's are required
Use Proc Freq to generate the list, list variables in a table statement if only specific variables are desired
Use ODS Table to capture the output and then format the output into a printable table.
*/
*Run frequency for tables;
ods table onewayfreqs=temp;
proc freq data=sashelp.class;
table sex age;
run;
*Format output;
data want;
length variable $32. variable_value $50.;
set temp;
Variable=scan(table, 2);
Variable_Value=strip(trim(vvaluex(variable)));
keep variable variable_value frequency percent cum:;
label variable='Variable'
variable_value='Variable Value';
run;
*Display;
proc print data=want(obs=20) label;
run;
