With a PROC FORMAT, if you create formatted values to have the same format
as missing values, it will consider them to be missing by PROC FREQ. That
doesn't seem to be the case with PROC MEANS, not sure why.
IE:
proc format lib=work;
value xformat
-999,.=.
other=[best12.]
;
quit;
data test;
input x;
format x xformat.;
datalines;
-999
9
259
.
21358
;;;;
run;
proc freq data=test;
tables x;
run;
produces the desired result [no -999], but
proc means data=test;
var x;
run;
does not. You could use the format to change the value [create a new
variable], but I suspect there's a solution in this direction, just not one
that I can think of at the moment.
