Symmetric and Asymmetric Rounding [PDF]

open access: yes, 2006
If rounded data are used in estimating moments and regression coefficients, the estimates are typically more or less biased. The purpose of the paper is to study the bias inducing effect of rounding, which is also seen when population moments instead of ...

Rounding error analysis of linear recurrences using generating series

open access: yesETNA - Electronic Transactions on Numerical Analysis, 2023
We develop a toolbox for the error analysis of linear recurrences with constant or polynomial coefficients, based on generating series, Cauchy's method of majorants, and simple results from analytic combinatorics. We illustrate the power of the approach by several nontrivial application examples. Among these examples are a new worst-case analysis of an

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 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 ...

Rounding error analysis for forward continued-fraction algorithms

open access: yesComputers & Mathematics with Applications, 1985
From authors' summary: There exist several algorithms for the calculation of a continued fraction. We will investigate the effect of data perturbations and rounding errors for some algorithms, using the ideas of Stummel's perturbation theory which is a forward error analysis.

Computing Integer Powers in Floating-Point Arithmetic [PDF]

open access: yes, 2007
We introduce two algorithms for accurately evaluating powers to a positive integer in floating-point arithmetic, assuming a fused multiply-add (fma) instruction is available.

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 ...
