(e) Values of frictional velocity dependence of the tested samples for the range of sliding velocities V = 0.0028 to 2.8 mm/s.
This will remove the dependence of the test-statistic on an underlying distribution.
Fisher's exact test was employed to assess statistical significance, and a multiple testing correction using the method of (Benjamini and Yekutieli, 2001), which assumes the statistical dependence of the individual tests, with a 10% cutoff was performed.
The dependence of the abrasion tests results on mechanical film properties, i.e. the nanoindentor hardness, was analyzed.
The significantly stronger correlation of SUV and HU (z = 2.41, p < 0.05) compared to ACC (kBq/ml) and HU can be attributed to the reduction of the dependence of the correlations tested on administered dose as a confounding variable in this analysis.
48 Based on 2×2 tables (Table 1), the vector y = (y11, y12, y21, y22) follows a multinomial distribution with a probability vector p = (p11, p12, p21, p22), where S, C, and π denote the specificity, sensitivity, and prevalence, respectively, whereas d1 and d2 quantify the conditional dependence of the two tests.
Yet, several focus groups pointed out that an increased usage of medical tests might also cause dependence of these tests for achieving reassurance and a healthy feeling.
Additionally, we ran simulations with the hazard ratio for mortality (HR mor) equal to 1.15 and 1.5, to investigate the dependence of each test statistic on the hazard ratio of the competing event.
Furthermore, the dependence of the overall t-test on the different within-group means is only caused by an inflation of the standard error estimate.
