According to Fischer (1974), item precision can be depicted by item information curves (or functions), which indicate the range over the measurement construct in which the item discriminates best among individuals.
Mean one-item and three-item VWM precision values, corrected for sensorimotor performance, were interrogated for effects of participant age using linear regression and partial correlation controlling for FSIQe.
Today, Atkinson turns up his nose at this sort of thing, seeking to fill his van with compact, high-value items, like precision photography tripods and shoes ("photographers are always breaking the shoes off their tripods") that he says will bring him an easy $300 to $400.
However, due to the inherent limitation of the ADAS-Cog items, the precision of the ADAS-CogIRT methodology in measuring language and praxis impairment is good only when a patient's performance is quite poor (Fig. 3d).
We investigated the relationship between FSIQe and mean three-item VWM precision, corrected for sensorimotor precision and standardized within each year group, using linear regression.
Singapore's economy has been hit by the collapse in demand for items like electronics, precision engineered goods and pharmaceuticals, the Trade Ministry said Tuesday.
And Switzerland is indeed a major economic power, thanks to its long tradition of financial services and high-quality, specialized manufactures of items such as precision timepieces, optics, chemicals, and pharmaceuticals, as well as of specialty foodstuffs such as Emmentaler cheese and milk chocolate.
They found that the manufactured items have good precision, accuracy and aesthetic appearance.
However, the standard error of the estimates was not larger compared to the other items, indicating acceptable precision of estimation.
