However, as the prevalence increases, the performance of the combinatorial designs quickly deteriorates, and for prevalence higher than 3% the signal is too dense to reconstruct, and the performance of the designs is roughly equivalent to simply assigning the wild-type allele to the entire group.
The formula presented adjusts prevalence for the performance of the screening instrument.
However, testing of fluids as an alternative to serum may be conducted with advantage for antibody screening of populations, at least for infections of high prevalence, once the performance of the particular method on specific well-characterized alternative fluid samples is evaluated.
To investigate the ability of individual difference factors to predict low prevalence search performance, we performed linear regression models.
We also performed this regression leaving low prevalence search performance out of the model.
The results of our regression analysis suggest that five factors (measures of visual WMC, attentional control, vigilance, high prevalence search performance, and the personality trait of introversion) were significant predictors of low prevalence search performance; a regression model with these five factors accounted for over 50% of the variance in low prevalence visual search performance.
The cognitive predictors that were entered into this model included high prevalence search performance, K, vigilance, and attentional control.
However, if high prevalence search performance is a good predictor of low prevalence search performance, then one could gather data about an individual's performance very quickly at a high prevalence rate and use that as a predictor of the unobserved low prevalence performance.
Finding that high prevalence search performance is a good predictor of low prevalence search performance would provide an efficient method for predicting who would be good at low prevalence search tasks.
Given these large individual differences in performance, they investigated whether individual differences in WMC could predict low prevalence search performance.
