The above two network thresholding schemes (absolute threshold and mean degree) are arbitrary thresholding schemes that might add bias for group and task comparisons and reduce the possibility of the reproducibility of the findings across studies from different research groups.
Some methods have been used more frequently than others: for example, absolute threshold shifts (Table 1), perhaps because they are more straightforward to apply than some of the other methods.
In Figure 2, the mean of individual medians was used to summarize group trends in absolute threshold. A 2 (reading type; between subject) x 2 (symptom type; within subjects) x 5 (level of symptom severity; within subjects) mixed-model ANOVA was conducted to evaluate the results.
Predetermined absolute luminance thresholds tested included 1) percent of scene pixels exceeding various absolute thresholds, and 2) DGI and DGP produced by first identifying glare sources based upon various absolute thresholds.
Aggregated absolute threshold nutrient profile labels like the Heart Check mark are implied nutrient content claims suggesting that a food, because of its nutrient content, may be useful in maintaining healthy dietary practices.
Gustatory masking at the lower absolute threshold is a reliable phenomenon, as J.
The thick solid line is the squared absolute threshold curve (obtained using data from Figure 3).
Furthermore, several studies have demonstrated that cardiovascular risk (mortality or major cardiovascular events) increases continuously and progressively throughout the whole range of BNP concentrations in patients with cardiovascular diseases (i.e., an absolute threshold for risk cannot be determined) (2).
Since sensitive assays and absolute threshold values of androgens have not been established for women, the panel offered the lowest-quartile cutoff as a "clinically useful, albeit arbitrary, criterion for establishing a diagnosis."
Although disk densities have been increasing at better than 60% per year since 1991 (when IBM introduced its magnetoresistive sensor read technology) and driving the cost per GB down from $5,320 to $18.42 in the process, the industry is concerned that the absolute threshold for conventional magnetic storage density might be only a few years away.
