I'm trying to transform a continuous variable that contains all positive values, using a variety of functions (See code).
logPAMIN = log (SCORE); log10PAMIN = log10 (SCORE); rootPAMIN = sqrt (SCORE); expPAMIN = exp (SCORE/10);
The LOG and LOG10 functions return an error message relatiing to an invalid argument.
Any ideas what's going on?
Thanks.
When this happens you'll get missing values. So you can filter your data and figure out what's going on yourself 😉
My guess - 0 or missing values.
data check;
set have;
where missing (logpamin);
run;
proc means data=check n min max;
var score;
run;

@Reeza You were correct. Zero values were being converted to missing. Thanks!
