Dear All

I have a time series dataset ranging from 1940 to 2000. I have to find the maximum value in series(wage) in the following way:

Maximum wage in 1940 to 1941
Maximum wage in 1940 to 1942
Maximum wage in 1940 to 1943
Maximum wage in 1940 to 1944

and so on till

Maximum wage in 1940 to 2000

How can I compute this value.
Thanks in advance

Thanks!

-rolling- worked. But If I am interested in
 
Maximum wage in 1940 to 2000
Maximum wage in 1941 to 2000
Maximum wage in 1942 to 2000
Maximum wage in 1943 to 2000

and so on till

Maximum wage in 1999 to 2000

How can i use -rolling- to compute this.

Thanks in advance.

Your most robust option is to use -rolling-. For example,

**********************************************
webuse lutkepohl2, clear
tsset qtr
rolling roll_max=r(max), window(1) ///
 recursive: su inv
**********************************************
