The results obtained show that there was a relatively strong correspondence between soils' series distribution and topographical properties. Mar 24, 2015 · This was confirmed by both a Mantel test and canonical correspondence analysis (CCA), which showed that, while all edaphic factors had some influence, pH and C:N ratio were the factors that most strongly correlated with microbial beta-diversity (Fig. 3D). pH and C:N ratio were also found to have the most significant correlations with changes in ... In applied statistics, canonical correspondence analysis (CCA) is a multivariate constrained ordination technique that extracts major gradients among combinations of explanatory variables in a dataset. The requirements of a CCA are that the samples are random and independent and that the independent variables are consistent within the sample site and error-free.

An interesting feature of correspondence analysis is its close connection to log-linear analysis. Goodman (1981b) showed that, under certain conditions, the estimates of the multiplicative row and column parameters in the log-linear model are approximately equal to the row and column scores of the first dimension in correspondence analysis .

Canonical Correspondence Analysis (CCA) Approach. CCA (aka Constrained Correspondence Analysis) is a direct gradient analysis method. It was developed and popularized by ter Braak (1986, 1987). Like CA, it maximizes the correlation between species and sample scores.

Whereas modernism led to a rejection and replacement of the so-called “premodern” commitment to Scripture as a divinely commissioned and unified theological corpus, canonical theology retrieves the canon as “canonical,” that is as: (1) divinely commissioned rule; (2) unified corpus; and (3) superintended by the Holy Spirit.The rotifer genus Brachionus proved to be a better indicator organism for these environmental gradients of trophic state and marine influence caused by anthropogenic impact than the entire zooplankton assemblage.
