We are not aware of any work that has looked at the effect of using different weightings for the same quality assessment tool to produce an overall quality score or that has been done in the area of diagnostic accuracy studies.
The analysis is relevant to endemic and chronic infections with prolonged periods of infectivity of affected animals, and uses different weightings of contacts to address disease scenarios of low, intermediate and high animal-level prevalence.
Equal weighting is the standard approach used in the absence of any compelling reason to apply different weightings and is not intended to imply that all elements used are considered of equal significance.
Innocenti's position concerning the weighting issue is subtle and complicated (UNICEF 2007, p.5): Equal weighting is the standard approach used in the absence of any compelling reason to apply different weightings and is not intended to imply that all elements used are considered of equal significance.
Four different controllers using different variance weightings, are optimized using the H2 and polynomial chaos technique.
Taking into account that by using different T1 and T2 weightings thrombus can be easily differentiated (Figure 1), it is possible that employing a series of pulse sequences would not only allow to detect coronary stenosis but also to gain insight into thrombus and plaque composition.
The two plans were hybrid using different D p weightings of 80%and20%0%, respectively.
(A) T-F interdependence estimates using Hamming-weighting window of the width w f = 0.1 s and varying-width smoothing window, w t = 0.1,0.37143,…,2 s, rows (B G) illustrate the T-F interdependence estimates using different lengths of the weighting and smoothing windows, respectively.
Moreover, biochemical information is codified by using different pair combinations of nucleotide-base properties as weightings (experimental molar absorption coefficient ε260 at 260 nm and pH=7.0, first (ΔE1) and second (ΔE2) single excitation energies in eV, and first (f1) and second (f2) oscillator strength values (of the first singlet excitation energies) of the nucleotide DNA RNA bases.
Regions with different distributions or where similar results are observed under different management or control scenarios will generate different weightings, and hence evaluations of the effectiveness of treatments will vary.
