Another type of error comes from the discretization step size of or in numerical computation, the discretization step size of or must be selected appropriately in numerical computations in order to describe short waves phenomena concerned to the target programs. This error would be also red...
Chapter 1 / Error in Numerical Method Double Precision (IBM 370) In a double precision, 8 bytes, or equivalently 64 bits, are used to store one real number. In this format 1 bit is used for sign, 7 bits are used for exponent, and 56 bits are used for mantissa. Grouping when the s...
Please note that the mean and mode are computed using all data. NA values are ignored in the computation of the mean but are considered a value in the mode function and may be returned as the mode if they are the most common value. If you want to exclude NAs when computing the mode,...
Finding outliers/errors in numerical data has also been studied. For example, Hellerstein [34] proposes to use the metric of MAD (median absolute deviation), which is from robust statistics and analogous to standard deviation to detect out- liers in numeric data. Multi-column correlation between...
This paper shows that the inverse chirp z-transform (ICZT), which generalizes the inverse fast Fourier transform (IFFT) off the unit circle in the complex plane, can also be used with chirp contours that perform partial or multiple revolutions on the uni
2.4 Numerical experiments In this section, we numerically verify (i) the quadrature error bounds shown in Table 1 on circles in 2D and spheres in 3D; and (ii) the variance of quadrature error under random translations. The reference values of the boundary integrals are computed by Mathematica ...

The paper develops a numerical method which allows error-free computation of the Moore-Penrose inverse of a matrix having rational elements. Multiple modulus residue arithmetic is used to avoid error that is inherent in floating-point arithmetic. The method is an improved form of one originally ...
Computation of partial derivatives through the working ja:math equations is tedious and error-prone, however. As a result, several data reduction schemes using different levels of approximation are implemented in various laboratories, some of which ignore certain sources of error while others use ...
