Hi,
I was wondering whether there is an easy way to assess the no. missing/null values in a field?
I use the following for numeric and string variables. Its fine for numeric variables, but the code for string variables returns a frequency table of values, if there is a lot of records and a string ID field the output can be massive. Is there a way to output a report of only the count of the number of missing values for each character variable?
thanks,
/* Asess numeric variables */
proc means data = Datafile n nmiss;
var _numeric_;
run;
/* Asess categorical variables */
proc freq data = Datafile;
tables _character_ ;
... just in case anyone was wondering!
proc format;
value $miss " "="missing"
other="nomissing";
run;
proc freq data=datafile;
tables _character_ / missing;
format _character_ $miss.;
run;
