= SAS Means =

A procedure for computing statistics.

<<TableOfContents>>

----



== Usage ==

{{{
proc means data=LIBREF.TABLE STATSLIST maxdec=2;
  var VARLIST;
  class CLASSVARLIST;
  ways 2;
run;
}}}

`STATSLIST` can be any combination of:

 * `mean`
 * `std`
 * `stderr`
 * `sum`
 * `median`
 * `min`
 * `max`



=== Class Statement ===



=== Ways Statement ===

The '''`WAYS`''' statement takes any number from 0 to the number of `CLASS` variables. A value of 0 ignores the classes. A value of 1 runs statistics for each single group. A value of 2 runs statistics for each combination of 2 groups. And so on.

----



== Output ==

To store the `STATSLIST` variables for each `CLASS` group, try:

{{{
proc means data=LIBREF.TABLE noprint;
  var VARLIST;
  class CLASSVARLIST;
  ways N;
  output out=LIBREF.TABLE2(drop=_FREQ_ _TYPE_);
run;
}}}

Note the '''`NOPRINT`''' option, which suppresses printing.

To explicitly name the `STATSLIST` variables, try:

{{{
proc means data=LIBREF.TABLE mean max noprint;
  var Price;
  class Region;
  ways 1;
  output out=LIBREF.TABLE2(drop=_FREQ_ _TYPE_) mean=MeanPrice max=MaxPrice;
run;
}}}
