Mean of a count

[billfriend]

I have data with several variables including store_id, location, and product_cat.  Store_Id ranges from 1-8, location ranges from 1-9 (representing outside, entrance etc.), and product_cat ranges from 1-8 (representing candy, cereal, etc).  I need the mean number of "displays/counts" per store by location and product_cat.  I'm unsure how to transform this data to get the correct information.

Please show how the data is arranged now, as in a SAS data step.  Then are layout of what the desired results would look like.

Help us help you.

Try a summary procedure such as PROC MEANS/SUMMARY.

You can add multiple variables into the BY statement, and SAS will break down the analysis by the variables in the BY statement.

This is great, thank you!  Quick question-I am not reporting by store. My table shells look like this:

Locations	Mean (SD)	Range
Outside
Entrance
EndCap A
EndCap B
Aisle
Edge
Checkout side
Checkout edge
Island
Food Product Categories	Mean (SD)	Range
Cereal
Candy
Chips
Cookies
Fruits and Vegetables
Fruit Drink
Soda
Beverages

I am confused as to what to report.  I can't just take the "by STORE_ID;" out.

Post some sample data and your expected output. Please post as a data step, see instructions here:

https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat...

You can also google a paper called ‘creating complex reports’ by Cynthia Zender that walks through how to create presentation ready tables.

I'm having a hard time getting this to work.  I have SAS version 9.4.  I downloaded the macro and have it opened in my SAS; I don't use macros that are this complicated very often, so it's a bit confusing.  Do I edit the top line?

%macro data2datastep(mydatasetname?,lib,outlib,file,obs,fmt,lbl);

[Reeza]

Don’t touch the macro code. Run it once and then close that program. 

Run through the instructions exactly first and then try it on your data.

[billfriend]

I ran the macro, closed it. I don't have SAS University Edition so I am confused about Autoexe.
I tried to run:
>%data2datastep(mydatasetname,sashelp,,10)
This kept giving me an error, sashelp.mydatasetname does not exit.

Also, I'm not worried about creating complex tables, I'm just unsure what to fill those table shells with. Thank you!

Top of the post:

%data2datastep(dsn, lib, file, obs);

dsn = input data set name, required

lib = library where input data set resides, optional

file = name of output file, optional

obs = number of obs to include in the data step, optional 

Lib, the second parameter is the library where the data set is stored. I'm assuming your data set is not in the SASHELP library but most likely the WORK library. Just leave it empty and it should work.
