Dear Torben,
Question nr 1: How do I do this in stata?
Answer nr 1 (please, consider that what follows refers to each one of your
years. I assume that the annual value a is 100):
set obs 12
g a=100/12
Question nr 2: How do I do it in stata if I want to assume a non-zero
variance still maintaining the sum of the monthly data equals the annual
data?
Answer nr 2: corr2data b, means(8.3333333)
sum a b
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
a | 12 8.333333 0 8.333333 8.333333
b | 12 8.333333 1 6.919311 9.956305
. total a b
Total estimation Number of obs = 12
--------------------------------------------------------------
| Total Std. Err. [95% Conf. Interval]
-------------+------------------------------------------------
a | 100 0 . .
b | 100 3.464102 92.37556 107.6244
--------------------------------------------------------------
HTH and Kind Regards,
Carlo

Oggetto: st: Data generating
Dear Statalist participants,
I have a list of annual data like
Year variable_X variable_Y ...
1900 a b
. . .
. . .
. . .
1950 c d
For some reasons, based on annual data alone, I am interested in generating
monthly data for the two or more variables, assuming the monthly data has
zero variance with the average value for each month amounting to annual
value divided by 12. That is, I need
Year variable_X variable_Y ...
1900M1 a/12 b/12
1900M2 a/12 b/12
1900M3 a/12 b/12
. . .
. . .
. . .
1900M12 a/12 b/12
. . .
. . .
. . .
1950M12 c/12 d/12
Question nr 1: How do I do this in stata?
Question nr 2: How do I do it in stata if I want to assume a non-zero
variance still maintaining the sum of the monthly data equals the annual
data?
Thanks in advance for your help.
