Error Control Matters

چکیده
Sometimes an ordinary differential equation (ODE) solver gives the results it should, even if they are unexpected or undesirable. To obtain correct, expected numerical results, both relative and absolute error control tolerances must be chosen judiciously. Here we attempt to clear up some possible misunderstandings regarding the performance of a popular ODE solver and error control.

Improving Wireless LAN Performance via Adaptive Local Error Control
Wireless links can exhibit high error rates due to attenuation, fading, or interfering active radiation sources. To make matters worse, error rates can be highly variable due to changes in the wireless environment. Researchers and developers have explored a wide range of solutions to optimize communication in this difficult error environment, including traditionalend-to-end solutions, link-laye...

متن کاملFamily Background, Ability and Student Achievement in Rural China –Identifying the Effects of Unobservable Ability Using Famine-Generated Instruments
This paper investigates the effects of family background on academic achievement in basic education (grade 1-9) in rural China, using information on a sample of children aged 9-12 in 2000 from Gansu, China. The instrumental variable method developed by Mason and Griliches (1972), and Blackburn and Neumark (1992) is applied to control for unobserved child ability. Scores of a cognitive ability t...
متن کاملError Matters: An Initial Exploration of Elementary School Children’s Understanding of Experimental Error
Error is a pervasive and inescapable aspect of empirical science, and it often plays a causal role in experimental outcomes. But little is known about children’s understanding of the causes and consequences of experimental error. In this article, we propose a new framework for characterizing experimental error and we use that framework to guide an empirical assessment of elementary school child...
