annual to monthly GDP conversion

[podarum]

Hi, I guess my 2 questions are first, how can I convert from annual GDP to monthly GDP.. some sort of extrapolation.  Secondly, anyone knwo if I do have let's say 1999 GDP = $1.75Bill and 2000 = $2.1Bill could I do an average like 1999.01 = $1.75Bill and 1999.02 = $1.75Bill or do I divide $1.75Bill into 12 so 1999.01=$145Mill and so on for each month??

Thanks

Look at PROC EXPAND (in SAS/ETS).
