Propagation of Uncertainty Rules for Estimating Uncertainty
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 … See more Let $${\displaystyle \{f_{k}(x_{1},x_{2},\dots ,x_{n})\}}$$ be a set of m functions, which are linear combinations of $${\displaystyle n}$$ variables $${\displaystyle x_{1},x_{2},\dots ,x_{n}}$$ with combination … See more This table shows the variances and standard deviations of simple functions of the real variables $${\displaystyle A,B\!}$$, with standard deviations In the columns … See more • Accuracy and precision • Automatic differentiation • Bienaymé's identity • Delta method • Dilution of precision (navigation) See more • A detailed discussion of measurements and the propagation of uncertainty explaining the benefits of using error propagation formulas and Monte Carlo simulations instead of simple significance arithmetic • GUM, Guide to the Expression of Uncertainty in … See more When f is a set of non-linear combination of the variables x, an interval propagation could be performed in order to compute intervals which contain all consistent values for the variables.
