Enrichment of GO annotations was calculated by using the proportion test in R [39].
A different proportion of persons discharged from the hospital or who died after receiving a diagnosis of SARI may have tested positive for influenza than the proportion tested by convenience.
Differences in prevalence were assessed by using the proportions test in R version 2.11.1 (www.R-project.org).org
Differences in the frequencies of medication groups, for example at primary diagnosis, application of steroids, or incidence of breakthrough infections when comparing the three patient groups (with n = 31, n = 32, and n = 30 patients), were tested by the k proportions test.
Two further metrics were applied, 1) a threshold-dependent omission rate (fixed value of 10) [37], which evaluates model success by assessing the proportion of test locations that fall into cells that were not predicted as suitable, and 2) Test gain, which can be interpreted as the average log probability of the presence samples used to test the model.
Item difficulty was characterized by calculating the proportion of test takers who achieved a passing score for each item.
GO enrichment was determined by a proportion test between the number of clones representing a GO term on the array compared to the number of differentially expressed clones representing the same GO term in a given comparison with a p-value cut-off of 0.05.
In a national sentinel network of laboratories, the median length of the rotavirus season decreased by 54%, the number of stool specimens submitted for testing decreased by 67%, and the proportion of test results positive for rotavirus declined by 69% after vaccination in the 2007-8 season compared to the 2000-2006 seasons [ 15].
p<0.05 by binomial proportion test.
Therefore the incidence was adjusted by decreasing the person-years of observation by multiplying it by the proportion of diarrheal episodes tested for RV, when such information was given.
