Dear list,
If I know the standard error for k1 and k2, is there anything I can call in
R to calculate the standard error of k1/k2? Thanks.
No, because it depends on the joint distribution of k1 and k2. Even if
you knew they were independent, that would not be sufficient (though you
could use the delta method to get an approximation in that case; look it
up).
