The similarity matrix was subjected to cluster analysis by unweighted pair group method for arithmetic mean (UPGMA) and a dendrogram was generated using the DARwin computer software Perrier et al.
Although dendrograms of both classes (Figures 6 and 5) show that there are easily separable clusters (three for class 'Malicious' and four for class 'Benign'), dividing data into subclasses does not lead to improved performance of C4.
0/1 matrix was used to calculate similarity as Neis coefficient and resultant similarity matrix was employed to construct dendrograms based on Unweighted Pair Group Method with Arithmetic Means (UPGMA) to infer genetic relationships and phylogeny.
In our study, this behaviour is clear in both 16S rRNA and 18S rDNA/rRNA DGGE dendrograms from kiwifruit orchard, which revealed a clear discrimination between INN and CON systems (Fig.
This method was applied to the NSGA-II results, giving the dendrogram shown in Figure 6.
The dendrogram derived following numerical analysis of the protein electrophoregrams between the different treatments in fish vs chicken is shown in Fig.
Findings were recorded in the form of dendrograms exhibiting the degree of similarity between isolates expressed in percentages.
At the upper level of the dendrogram two main shapes of pyramids can be seen.
However, primary and secondary forest samples did not form separate clusters within any of these trees but instead were almost completely interspersed throughout each dendrogram (Fig.
Both multidimensional scaling and dendrogram analysis reveal results similar to well-known language groupings, and also suggest a finer level of detail on these relationships.
The results for each antimicrobial drug were coded in binary data (0 for susceptible and intermediate phenotypes and 1 for resistant ones), and we computed the corresponding matrix using NTSYS-pc software, applying the Jaccard similarity coefficient and the unweighted pair group method with arithmetic mean (UPGMA) for clustering and dendrogram construction (Sneath & Sokal, 1972).
