Dear Stata listers,
I am using Stata 12.1 64
for linux.
I want to drop duplicates
of (x y z) variables after getting the total of variable M.
Below, you may see what I
do.
My problem is that totals
before and after are not equal. Is this because I make something
wrong?
Any help would be greatly
appreciated.
.bysort x y z: egen
TOTAL=total(M)
.bysort x y z: replace
TOTAL=. if _n!=[1]
.total M TOTAL
Total estimation
Number of obs = 18825
----------------------------------------------------------------
| Total
Std. Err. [95% Conf. Interval]
---------------+------------------------------------------------
M | 79710.59
16778.85 46822.54 112598.6
TOTAL| 84234.31
16779.48 51345.02 117123.6
----------------------------------------------------------------
79710.59 != 84234.31
