Hi
I used R to demean values.
(1)
dat=c(24,34,44,55,....)
s=dat-mean(dat)
sum(s)
1.421085e-13
So the sum is not zero!
(2)
Besides, FSL GLM only takes 6 digits after the point.
So it will only record 1.000000e+00 for example....
So how do I solve these problems? ( The non-zero sum problem and The unequal digits problem )
THANKS A LOT!
