A simple random-number generator for a rectangular distribution function is shown to provide an econimical and fairly efficient means of simulating the effects of using a normal distribution function. open in overlay 1Present address: Department of Physics, University of Albama, AL 35486-1921, U.S.A.

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 to monte carlo analysis project management the combination of variables in the function. The uncertainty u can be expressed in a number

usually written as a percentage. Most commonly, the uncertainty on a quantity is quantified in terms of the standard deviation, σ, the positive square root of variance, σ2. The value of a quantity and its error are then http://www.sciencedirect.com/science/article/pii/0097848584800078 expressed as an interval x ± u. If the statistical probability distribution of the variable is known or can be assumed, it is possible to derive confidence limits to describe the region within which the true value of the variable may be found. For example, the 68% confidence limits for a one-dimensional variable belonging to a normal distribution are ± one standard deviation from the value, that is, there is approximately a 68% probability that the true value https://en.wikipedia.org/wiki/Propagation_of_uncertainty lies in the region x ± σ. If the uncertainties are correlated then covariance must be taken into account. Correlation can arise from two different sources. First, the measurement errors may be correlated. Second, when the underlying values are correlated across a population, the uncertainties in the group averages will be correlated.[1] Contents 1 Linear combinations 2 Non-linear combinations 2.1 Simplification 2.2 Example 2.3 Caveats and warnings 2.3.1 Reciprocal 2.3.2 Shifted reciprocal 3 Example formulas 4 Example calculations 4.1 Inverse tangent function 4.2 Resistance measurement 5 See also 6 References 7 Further reading 8 External links Linear combinations[edit] Let { f k ( x 1 , x 2 , … , x n ) } {\displaystyle \ ρ 4(x_ ρ 3,x_ ρ 2,\dots ,x_ ρ 1)\}} be a set of m functions which are linear combinations of n {\displaystyle n} variables x 1 , x 2 , … , x n {\displaystyle x_ σ 6,x_ σ 5,\dots ,x_ σ 4} with combination coefficients A k 1 , A k 2 , … , A k n , ( k = 1 … m ) {\displaystyle A_ σ 0,A_ ρ 9,\dots ,A_ ρ 8,(k=1\dots m)} . f k = ∑ i n A k i x i or f = A x {\displaystyle f_ ρ 4=\sum _ ρ 3^ ρ 2A_ ρ 1x_ ρ 0{\text{ or }}\mathrm σ 9 =\mathrm
