Dear all, Dear Michael & Edward,
I'm currently on the way to England, thus only a short note:
The error or an inverse is a special case of the error of a ratio. A search
for "error propagation" in the internet yields
hundreds of hits. There are also some discussions about correlation bewtween
involved quantities.
If y=A/B with given errors of A and B then the absolute error of y is y *
sqrt [(errA/errB)^2 + (errB/B)^2]
If A=1 you get error of y is y*errB/B, since the error of a constant is 0.
I compared the results with the errors I got from Marquardt if I fit a*
exp(-Rt) instead of a* exp(-t/T) by eye up to
a number of digits.
I hope, I did it right.
Best regards,
Peter
