There are few strong inter-element correlations within these data. The highest correlations for the shallow groundwaters were between Na and B (linear data, r =0.59, n=3203) and amongst the alkaline earth metals (r up to 0.71). Arsenic was not strongly correlated with any of the solutes given in Table 4 - the highest correlation was between arsenic and the alkaline earth metals and with phosphate but these were weak in all cases (r <0.1). 

Assay Development and Validation. Reproducibility of this ELISA assay was determined based on a set of clomazone standards that were run on different plates on the same day (intra-assay) and on different days (inter-assay). The intra-assay coefficient of variation of the standards changed from 1.5 at the highest clomazone concentration (250 ppb) to 22 at the lowest concentration of 1.4 ppb. The coefficient of variation(CV) at clomazone rate of 12.5 ppb was 10. Similar values were obtained for the inter-assay variability, with the CV of the 1.4 ppb concentration being 22.5, and the CV for the 250 ppb concentration being 2.7. The CV for the 10 ppb concentration of clomazone was about 5 between tests. Analysis of the data for this range of clomazone concentrations indicates that there is good correlation (r =0.97) between the log of the concentration of clomazone and percent inhibition in the assay when the linear regression equation was used. Based on these results, the limit of the test s sensitivity was defined as 2 ppb (10 ppb in soil) and the limit of detection was set at 1 ppb. 

The second problem, having decided that a correlation is real, concerns the choice of which descriptor to eliminate. One approach to this problem is to delete those features which have the highest number of correlations with other features. This results in a data matrix in which the maximum number of parameters has been retained but in which the inter-parameter correlations are kept low. Another way in which this can be described is to... 

As in CeCug, the magnetic correlations in CeRu2Si2 can be suppressed by the application of an external field (in the c direction). The field dependence of the magnetic signal up to 10 T at T=1.5K is reproduced in fig. 56. The inter-site contribution disappears above the metamagnetic transition at 8.3 T and at the highest...
