Error propagation in reciprocity variable

WebOct 17, 2024 · Viewed 272 times. 1. I have two measurements X = x ± σ x , Y = y ± σ y, where x, y are the mean values of X and Y and σ x, σ y are their corresponding uncertainties. The covariance matrix ( Σ) for them is the following: Σ = ( σ x 2 σ x y σ y x σ y 2) Also I have a number Z = z ± σ z. Suppose that I create a vector V = { X, Y } and ... WebMay 3, 2024 · It is important to note though that the fit itself is different when accounting for errors in the measurements.

WebMay 11, 2024 · $\begingroup$ Besides, I think this makes more sense, because this follows from the product rule of differentiation, hence for small errors it's an accurate estimation of propagation. $\endgroup$ – Ritam_Dasgupta In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them. When the variables are the values of experimental measurements they have uncertainties due to measurement limitations (e.g., instrument precision) which propagate due to the combination of variables in the function.
