Question on proc rank

[newone]

I have variables asset, year. I want to rank asset by year, that is to rank asset within each year. There is no tie in the asset. I want to have four groups of equal sizes based upon the rank of asset.  I used proc rank procedure. I used groups=4 option. But in the result, the number of obs in each group is not equal. Why are they not equal? How to do this correctly?Thanks.
