In the present work, the sum of test substance contained in first and second skin washings and donor chamber extraction was regarded as the 'non-absorbed dose.' The 'absorbed dose' was considered to be the amount of test substance within the receptor fluid at exposure termination and the extraction of the receptor chamber.
The optimal threshold is defined as the one that leads to the highest sum of test sensitivity and specificity (within this sum, different weights may be given to sensitivity and specificity).
Computation time for all steps of the CisFinder algorithm ranged from 5 to 120 s (Supplementary Table S1), with median time 38 s needed to process a 7.5 Mb sequence (sum of test and control sequences).
Regarding the first two sections, the differences between the sums of test scores for the three planning groups did not reach any significance, which suggests that their English proficiency level was the same (see Table 1).
Assuming that the genes are independent of each other, the sum of effective tests over all genes was 285.
Childhood cognitive ability at age 8 years was represented as the sum of four tests of verbal and non-verbal ability devised by the National Foundation for Educational Research.
If the above TDTs are considered as independent investigations, the corresponding P values will also be independent and the sum of three tests is distributed as χ.
However, given the potential of GC aetiology to differ by anatomical subsite, subgroup analyses were performed for total sum of carotenoids (test for heterogeneity P=0.33), retinol (test for heterogeneity P=0.44) and α-tocopherol (test for heterogeneity P=0.84).
So we provide the results of Wilcoxon rank sum test which tests the median rather than the mean of compared groups in the figure.
Our students are more than the sum of their test scores, and research clearly shows that an overemphasis on test scores will not result in increased learning, increased well-being, or greater success.
Significance was assessed against the null model by chi squared test of residual deviance, goodness-of-fit by unweighted sum of squares test, and predictive ability by calculation of the c-statistic.
