PROC MEANS PROCEDURE

CeliaAlonso — Mon, 11 Jun 2018 08:47:19 GMT

Good morning,

I have a problem with the PROC MEANS procedure.

The problem is that I have a table with two variables

-cod (is a code, numeric)

-cod2 (is another code, numeric)

What I want to do is to make a PROC MEANS summarizing by cod and cod2. But PROC MEANS procedure gives me the variables _TYPE_ and _FREQ_ summarizing the variable cod and then the variable cod2 instead of doing together.

My code is:

proc means data=data.table1 noprint;
class cod cod2;
output out=data.table2;
run;

Please provide test data in the form of a datastep (or use sashelp.xyz), as this helps us see what you have, and show what you want out. You say you want to summarise cod and cod2, to which statistics? _type_ and _freq_ are SAS derived variables, you can get stats out by (going to assume a few basic ones):

proc means data=data.table1 noprint; 
  var cod cod2;
  output out=data.table2 / n=n mean=mean median=median stddev=stddev min=min max=max; 
run;

This will give you a table (assumption as not seen data!) with cod and cod2 on two obs with the given stats as variables. You can read in the manual further examples and full documentation.

I get the solution it was doing this:

proc summary data=data.table1 print;
by cod cod2;
output out=data.table2;
run;

Thanks for help anyways

Several ways:

Use the NWAY option on the PROC MEANS statement so you only have the highest level.
Use the WAYS or TYPES statement to explicitly control the levels
Use a BY statement instead of CLASS
Use a PROC SQL instead if only doing a single statistics it's relatively easy.
