Frequency Using Proc Sql

[ Edited ]

Hello,

 

I want to do a frequency on a variable using proc sql.

I am doint count(VariableName) and also group by (VariableName) but it does not count the records where there is no value.

 

I am looking for something equivalent to the missing option in proc freq.

 

Here is my code:

data have;
input id Gender $;
datalines;
1 M
2 F
3 M
4 .
5 .
6 F
;
run;
proc sql;
select
Gender
,count(Gender) as frequency
from have
group by Gender
;quit;

The output is:

Gender  Frequency

           0

F         2

M        2

 

I want the output to be like:

Gender Frequency

           2

F         2

M        2

I was able to get this done but I am sure there is a better way to do it: Please suggest

 

proc sql;
create table freq as
select 
Gender
,sum(freq1,freq2) as frequency
from (	select 
		Gender
		,nmiss(gender) as freq1
		,count(Gender) as freq2
		from have
		group by Gender
		)
;quit;

Better way: use PROC FREQ

There is a valid reason to not use PROC FREQ -- maybe -- and that's if your data is in a database and you want the SQL work to push down to the database instead of bringing the data records into SAS.

 

However, that's not as true as it once was.  PROC FREQ can push work down to the database in SAS 9.3 and later, as long as you're using a SAS/ACCESS library engine to get to it.

Change it to PROC FREQ. 

 

Change it to count everything, not just Gender. 

In the future post your code in a legible format, the post above requires edits which is a pain. 

 

proc sql;select Gender,count(Gender) as frequencyfrom havegroup by Gender;quit;

The easy way is:

 

proc sql;
select 
    Gender,
    count(*) as frequency
from have
group by Gender;
quit;
