Concordant ranked

The value setting of the descriptors, within the sets. This is illustrated in Table 3 where the value setting of both Dose and SpArea shows several zero values in pairs and thus many equal objects in Set 2. This tends to reduce the number of concordant rankings and thus the potential number of rankings, which can be compared with rankings done in Set 1. 

More or less internal correlation within the variable in a set is critical for the number of concordant rankings within each set and thus also for the potential correlation between the two sets. 

ReproducibiUty in a primary HTS even with a good a/ (quality metric) >0.5 is an issue [9]. The concordance in a tripUcate HTS with identical target, identical screening format and identical compounds seldom exceeds 65%. Problems persist post primary HTS. IC50 rankings and selectivity panels can be seriously flawed if nominal rather than actual concentration is used. AH competent drug discovery... 

The ELECTRE family has been extended frequently to improve the original method and develop methods for different applications. ELECTRE II aims at ranking alternatives. It constructs a downward and an upward ranking in a multi-step procedure based on a strong and a weak outranking relationship and consequently requires two pairs of concordance and discor-... 

The obtained results facilitate constructing the rank graph. However, prior to that, one should determine the degree of opinion concordance of all the researchers by the concordance coefficient ... 

From Table D for a=0.05 and degrees of freedom f=7, the tabular value is X7.95%=14.1. Since the calculated value of, y2 criterion is above the tabular value, the hypothesis on concordance of the researchers opinions is accepted. This conclusion allows us to construct the rank graph in Fig. 2.18. The rank graph clearly shows an equal distribution, so these eight factors should be included in the active experiment for factor selection. 

A study about the effect of twelve factors of material preparation with regard to fiber tensile strength was done in the textile industry. Four researchers were asked about the prior ranking of the factors. The rank matrix obtained on the basis of a research poll is shown in Table 2.14. Check the concordance of researchers opinions and choose the significant factors for the next step of experimental research. 

In a process of chlorinating titanium, seven technological factors were suggested to be analyzed. Five researchers were asked prior to ranking of the factors. The rank matrix is shown in Table 2.15. Determine the concordance coefficient for the researchers opinions. 

The selection of factors from the work [16] was done hy the significance of their effects on caoutchouc drying and after processing the opinions of eighteen researchers. The analysis included these eleven factors Xi inlet and outlet moisture ratio X2 pH value in the sixth apparatus X3 pH value in the seventh apparatus X+ NaCl consumption X5 serum consumption in the sixth apparatus X6 serum consumption in the seventh apparatus X serum temperature X8 latex type X9 fat content in caoutchouc X10 latex fat consumption on machine and Xu quantity of latex on the surface. Outcomes of the ranking of the factors are shown in Table 2.16. Determine the concordance coefficient and check its significance. 

Sixteen factors were defined in the process of refining petroleum oils. By the method of prior ranking, determine the concordance coefficient and check its significance. Concordance of data from reference literature is checked based on ranking outcomes shown in Table 2.17. 

The individual panelists ranking of the four standards should not be influenced by the presence of two extra, clearly identifiable items, and the panel could therefore be tested for its ability to rank the standards correctly. This was done by calculating the "coefficient of concordance", as described by e.g. Moroney (12). The SR-values used in these calculations were the SR-values obtained after omitting the two samples from each individual ranking and the null-hypothesis for the test was that the actual SR-values should be equal to the SR-values which would have been obtained if all the panelists had ranked the standards correctly.

Two partial ordered sets are defined (1) Set 1, composed by DetFreq and MedMax as shown by the Hasse diagram in Fig. 1 (2) Set 2 composed by Dose and SpArea. Both concordant and discordant rankings are com-... 

These observations suggest robustness in the nature of the patterns, and a sharpening of the patterns with increasing concordance of indicators. The rank correlation (after Spearman) is 0.411 between upland and lowland in-...
