Average monthly Price

[JFario09]

Hi All

I am trying to calculate AVERAGE MONTHLY PRICE using the PROC SQL Code but stryggling to get the right coding.

The data looks like this :

Dates                    Amount

01Jul1994            1000

02MAY1995         1500

10MAY1995         2000

09JUN1995         3000

27JUN1995         3500

.

.

.

.

.

.AND SO ON FOR DIFFENRENT MONTHS IN DIFFERENT YEARS.

How to go abou it? Any suggestion will be helpfull

Thanks a ton in advance.

Create a variable called MONTH, you can use the MONTH function in SAS to do this. Also create a variable called YEAR, using the YEAR function in SAS.

Then run PROC MEANS or PROC SUMMARY with YEAR and MONTH as CLASS variables.

Something like:

proc sql;
  create table WANT as
  select MNTH,
         avg(AMOUNT) as AVG
  from   (select month(DATES) as MNTH,AMOUNT from HAVE)
  group by MNTH;
quit;

Something like

proc sql;
create table want as
  select put(dates,yymmn6.) as yymm, mean(amount) as mean_price
  from have
  group by calculated yymm
;
quit;

Certainly a superior method than what I described above.
