Figure 5

The prediction of hybridised DNA of the groups beneath the node of E. coli and Shigella isolates. The plot shows cross-validation results obtained by a regression model, which was trained only on signal intensities of probes associated to contrasted groups (x-axis). Filled circles indicate the predicted ratios of DNA in test samples of respective groups and the error bar indicates the cross-validation error of each prediction. The contrasted pathogroups comprise all integrated E. coli pathotypes as well as Shigella and non-pathogenic E. coli.
