I am working with a calibration curve
(http://en.wikipedia.org/wiki/Calibration_curve) and I want to evaluate the
use of 3 point curve instead 5 ponit curve with excel.
I have 5 point and 3 point (3 of the 5 points) curve and I use regression
analysis to obtain the following function Y= mx + b, and when I use 5 or 3
point the parameters m and b are similar. I think the use of the intersection
and slope error to evaluate what its better, but may be there are better ways
of evaluate it
thanks in advance
