Precision and accuracy of foundry dust exposure estimates from air sampling data.

Accuracy and precision in sampling hyporheic fauna

A series of interstitial faunal samples was taken from a riffle in the Speed River, southern Ontario, Canada, to compare the field performance of four hyporheic samplers: the standpipe, colonization, and freeze corers and a pump sampler. Each of the samplers proved useful for collecting purely qualitative data, but statistical differences in some of the measured quantitative parameters were ide...

AccucheckInform II: About Its Accuracy and Precision

Reporting of precision of estimates for diagnostic accuracy: a review.

among 16-19 year olds than any other age group. Overall attendances at sexually transmitted disease clinics have gradually risen since 1988, and increased use of services may have accounted for some of the 1994-6 rises, which continued into 1997. However, it seems unlikely that the pronounced rise could be attributed solely to a sudden widespread increase in clinic use. There is substantial sex...

Accuracy/Precision of USNO Predicted Clock Estimates for GPS Satellites

The United States Naval Observatory (USNO) Earth Orientation Department GPS Analysis Division (GPSAD) processes data from hundreds of GNSS receivers daily, computing multiple GNSS carrierphase-based product sets 365 days/year. Quantities estimated typically include high-precision (1-3 cm) GNSS satellite orbits/clock corrections, receiver clock corrections, station coordinates, earth-orientation...

Precision and accuracy of divergence time estimates from STR and SNPSTR variation.

Inference of intraspecific population divergence patterns typically requires genetic data for molecular markers with relatively high mutation rates. Microsatellites, or short tandem repeat (STR) polymorphisms, have proven informative in many such investigations. These markers are characterized, however, by high levels of homoplasy and varying mutational properties, often leading to inaccurate i...
