CCPA is not so popular among researchers in other fields.Jul 1, 2011 · Canonical Correspondence Analysis (CCA) was used to summarize the data set and to evaluate the expected relationships. The results obtained show that there was a relatively strong correspondence between soils' series distribution and topographical properties. (Detrended) canonical correspondence analysis is an efficient ordination technique when species have bell-shaped response curves or surfaces with respect to environmental gradients, and is therefore more appropriate for analyzing data on community composition and environmental variables than canonical correlation analysis.
