error propagation - hope it is correct subject
Dear all
Please, can you advice me how to compute an error, standard deviation or
another measure of variability of computed value.
I would like to do something like:
var(y) = some.function(var(x1),var(x2),var(x3))
for level F1 (2,3,...)
Let say I have some variables - x1, x2, x3 (two computed for levels of factor F
and one which is same for all levels) and I want to compute
y =
