A Note on the Perturbation of arithmetic expressions

open access: yesمجلة بغداد للعلوم, 2016
In this paper we present the theoretical foundation of forward error analysis of numerical algorithms under;• Approximations in "built-in" functions.• Rounding errors in arithmetic floating-point operations.• Perturbations of data.The error analysis is ...

Stochastic Rounding: Implementation, Error Analysis, and Applications [PDF]

open access: yes, 2021
Stochastic rounding randomly maps a real number to one of the two nearest values in a finite precision number system. First proposed for use in computer arithmetic in the 1950s, it is attracting renewed interest.

ANALYSIS OF ROUND OFF ERRORS WITH REVERSIBILITY TEST AS A DYNAMICAL INDICATOR [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2012
We compare the divergence of orbits and the reversibility error for discrete time dynamical systems. These two quantities are used to explore the behavior of the global error induced by round off in the computation of orbits. The similarity of results found for any system we have analyzed suggests the use of the reversibility error, whose computation ...

Relative distance—an error measure in round-off error analysis [PDF]

open access: yesMathematics of Computation, 1982
Olver ( SIAM J. Numer. Anal. , v. 15, 1978, pp. 368-393) suggested relative precision as an attractive substitute for relative error in round-off error analysis. He remarked that in certain respects the error measure

Randomized Low Rank Matrix Approximation: Rounding Error Analysis and a Mixed Precision Algorithm [PDF]

open access: yes, 2022
The available error bounds for randomized algorithms for computing a low rank approximation to a matrix assume exact arithmetic. Rounding errors potentially dominate the approximation error, though, especially when the algorithms are run in low precision

The R Package hmi: A Convenient Tool for Hierarchical Multiple Imputation and Beyond

open access: yesJournal of Statistical Software, 2020
Applications of multiple imputation have long outgrown the traditional context of dealing with item nonresponse in cross-sectional data sets. Nowadays multiple imputation is also applied to impute missing values in hierarchical data sets, address ...

Design and Implementation of a System-on-Chip for Self-Calibration of an Angular Position Sensor

open access: yesApplied Sciences, 2019
In this study, a novel signal processing algorithm and hardware processing circuit for the self-calibration of angular position sensors is proposed. To calibrate error components commonly found in angular position sensors, a parameter identification ...

The visual analog rating scale of health-related quality of life: an examination of end-digit preferences

open access: yesHealth and Quality of Life Outcomes, 2005
Background The Visual Analog Scale (VAS) has been extensively used in the valuation of health-related quality of life (HRQL). The objective of this paper is to examine the measurement error (rounding) explanation for the higher prevalence of VAS scores ...
