Errors in statistical analysis and questionable randomization lead to unreliable conclusions.
Dear Editor, We read with interest the paper, “The effect of food service system modifications on staff body mass index in an industrial organization”[1]. We noticed several substantial issues with data and calculations, calling into question the randomized nature of the study and validity of analyses. The distribution of baseline weight was significantly differentbetween groups (p-value = “0.0...

متن کاملCorrecting Response Failure Errors in Multi-Objective Optimisation in Unreliable Distributed Computing Environments
Population-based, multi-objective optimisation algorithms are increasingly making use of distributed, parallel computing environments. In these cases it is a commonsense precaution to consider the possibility of a variety of failures. In particular, errors caused by response failures are more prone to arise than in homogeneous parallel computers. While masking errors using redundant computation...
متن کاملConcerns about unreliable data from spotted cDNA microarrays due to cross-hybridization and sequence errors.
We discuss our concerns regarding the reliability of data generated by spotted cDNA microarrays. Two types of error we highlight are cross-hybridization artifact due to sequence homologies and sequence errors in the cDNA used for spotting on microarrays. We feel that statisticians who analyze microarray data should be aware of these sources of unreliability intrinsic to cDNA microarray design a...
متن کاملUnreliable Knowledge
There is a virtual consensus in contemporary epistemology that knowledge must be reliably pro duced. Everyone, it seems, is a reliabilist about knowledge in that sense. I present and defend two arguments that unreliable knowledge is possible. My first argument proceeds from an observation about the nature of achievements, namely, that achievements can proceed from unreliable abilities. My seco...
