Dear all,
I'm stuck with something that I think you may help me : )
I have a data set on a monthly basis like this one below:
Identifier Month Share outstanding
A 1 .
A 2 .
A 3 10000
A 4 .
My problem is that the variable "share outstanding", appears only once for each quarter.
I need to fill missing values of other months (in the specific quarter) with the maximum value of quarter
For instance, in the example above, in month 1 and 2 "share oustanding" should be 10000 (the maximum of that quarter).


Do you have any siggestions?
I tried many ways but I faced lots of problems.
The easiest way should be a carrybackward, nevertheless stata seems to not have this command.

Many thanks in advance
