Sensitivity coefficients The partial derivatives are the sensitivity coefficients for the associated components. Principles of Instrumental Analysis; 6th Ed., Thomson Brooks/Cole: Belmont, 2007. The idea is that given measurements with uncertainties, we can find the uncertainty on the final result of an equation. Since at least two of the variables have an uncertainty based on the equipment used, a propagation of error formula must be applied to measure a more exact uncertainty of the More about the author

Starting with a simple equation: $x = a \times \dfrac{b}{c} \tag{15}$ where $$x$$ is the desired results with a given standard deviation, and $$a$$, $$b$$, and $$c$$ are experimental variables, each The idea behind Monte-Carlo techniques is to generate many possible solutions using random numbers and using these to look at the overall results. In the above case, you can propagate uncertainties with a Monte-Carlo method by doing the following: randomly sample values of $$M_1$$, $$M_2$$, and $$r$$, 1000000 times, using the means and standard In effect, the sum of the cross terms should approach zero, especially as $$N$$ increases. http://www2.mpia-hd.mpg.de/~robitaille/PY4SCI_SS_2014/_static/Practice%20Problem%20-%20Monte-Carlo%20Error%20Propagation.html
