Open image in new window Figure 7 Cell viability index (arbitrary unit) assessed in SACCH and SACC compared with parent molecules and control.
Had either of the assessments had a zero reliability (in effect producing random numbers), or been reliable but assessing arbitrary material of no relevance to medicine, then performance of the two assessments would have been uncorrelated.
Even worse, the conditions for earning a grade are, to a large extent, arbitrary, with different professors assessing students with different weightings for different courses.
An unbiased metric of relatedness is crucial as curated hierarchies of classifications and ontologies are arbitrary and inaccurate in assessing relations between genesets.
The geometric-Poisson approximation offers a less arbitrary method of quickly assessing the likelihood of direct transmission without requiring computationally intensive Monte Carlo sampling strategies.
The cut-off used for assessing preload dependence with quantitative dIVC was 18% [ 7]: this is an arbitrary value that correctly evaluates the majority of patients.
Finally, we applied this tool to assess arbitrary alternative arrangements of the lattice model (Figure 3).
Calibration before and after correction, i.e. accurate classification into arbitrary strata, was assessed with the Hosmer-Lemeshow-Test. Treating culture as reference, the rapid diagnostic test had positive predictive values of 64.8% and 54.0% in derivation and internal validation corhorts with prevalences of 2.3% and 1.7%, respectively.
The current core curriculum guidelines suggest that gastroenterology fellows should perform a minimum of 130 EGDs and 140 colonoscopies before assessing aptitude, though these benchmarks are arbitrary.
However, three interrelated methodological issues that may compromise their information potential and statistical rigour are common to these studies: 1) the arbitrary choice of the assessed genetic diversity level, 2) the lacking assessment of how well genetic diversity was sampled, and 3) the choice of SDM projection scales relative to the sampling resolution.
