Concordant pairs and discordant pairs are used inKendall’s Tau, forGoodman and Kruskal’s Gammaand inLogistic Regression. They are calculated forordinal (ordered) variablesand tell you if there is agreement (or disagreement) between scores. To calculate concordance or discordance, your data must ...
; we employed the package Irr to assess consistency among evaluators; FactoMineR to perform the CA and the HCPC; and DeskTool to calculate the Cramer’s V values. For all statistical tests, an alpha level of 5% was used. Results Food lists and evaluators The list of marketed foods and ...
The formula to calculate the Aitchison distance between two generic vectors x and y of length m is: dA(x,y)=1m∑i=1m−1∑j=i+1m(lnxixj−lnyiyj)2 (9) As for SMAPE, we computed Aitchison distance on CPM transformed data. For each dataset and for each pipeline,...
To assess the agreement in the order of gene sets reported as differentially enriched when analyzing replicate datasets of the same size using a method ψ, we use Kendall’s coefficient of concordance [24]. The Kendall’s coefficient of concordance ranges between 0 and 1, with 0 indicating no...
A business case to calculate the break-even point of producing safe faeces samples for FMT was determined for the NDFB. We considered (i) recruitment, screening, and selecting of suitable donors, (ii) donation of faeces by donors and periodic rescreening, (iii) assessment of eligibility of ...
Cox proportional hazards regression methods were used to calculate the concordance (C-) statistic, a measure of discrimination. Results Of 18,397 TJAs included, 98.9% were alive 1 year postoperatively. For mortality, all models had concordance between 0.76 and 0.79, with the FI + ASA + CCI ...
Densities were then used to calculate the target number of syllables needed for each sub-corpus by dividing the baseline (Korean) syllable count by the SID for each of the other languages. The resulting figures are again shown in table 1. As the word counts of table 1 indicate, although ...
My other question is: are 5000 items out of 100000 sufficient to give us enough confidence in the 'agreement' that we observe? E.g. how would we calculate the minimal number n of items to pre-test in both assays to reach a significance p<0.05? But in fact, isn't the significance re...
The repercussions of an accident are of a varying nature and although it is not overly complex to calculate the direct economic impact1, 2 such as loss of earnings or cost of present and future medical expenses, difficulties arise when dealing with non-economic consequences such as pain, physic...
The fact that a gene that reduces population fitness can spread is the basis for the strategy of population suppression. In this simple case of a dominant functional gene it is straightforward to calculate the genetic load the spread of the DEG places on the population [20]. At equilibrium, ...
