That could be down to an administrative error in implementing the ban, or even a refusal to comply, say due to contention about Russia's role in Syria — we don't really know at this point".
We made an error in implementing the quality-of-life component and included only the first 12 items, but fortunately these items sample the full range of item locations on the quality-of-life scale, as described by the PRIMUS developers [ 16]].
In biology, however, the multitude of interactions underlying the processes we investigate (photosynthesis, decomposition, growth, cellular respiration) are so complex, and involve live organisms responding with inherent variation, that unanticipated results are frequently due to variability that cannot be controlled in our lab setting and are not due to errors in implementing procedures.
Other reasons were exclusive agreement to clinic-ePRO at the hospital (25%%), poor general condition (13.3 %), logistical problems or errors in implementing protocol (6.7 %), speech problems (3.3 %), and in some rare cases, language barriers, technical barriers, or treatment discontinuation (1.7 % each) (see Fig. 3).
There are thus real incentives to develop a systematic approach to construct a mathematical programming model in order to reduce the chance of human errors and to ensure operational efficiency in implementing the resulting schedules.
These differences (model errors) are due to embedded assumptions and differences in implementing the discrete forms of the equations.
A controlled robotic work station helped not only in implementing the sticker model but also in reducing error rates [49].
We identified genes differentially expressed in AAA [see additional file 1: Table I] using the Illumina custom error model implemented in BeadStudio.
This rating procedure basically replaced the verification phase (i.e. overt registration of errors whenever the participant felt he or she had made a response error), as implemented in the main EEG experiment.
The comparison of the gene expression between the two strains was performed as follows: Microarray data were imported into the GeneSpring GX version 7.3.1 software (Agilent Technologies, CA, USA) and initial background subtractions were performed based on negative controls and intensity-dependent (Lowess) normalization using the replicate cross-gene error model implemented in the software.
If a homoscedastic error structure (additive error) was implemented in run1.mod and run2.mod, the plot will show larger residuals at higher individual predictions.
