Partial Mantel Test
The partial Mantel test requires three matrices, the main matrix, a second matrix, and a control matrix. The null hypothesis is of no relationship between the main and second matrices, after controlling for the relationship with the third (control) matrix. If we call the main matrix Y, the second matrix X, and the control matrix C, then we seek the partial correlation between X and Y while controlling for C.
A hilltop plot is a way of showing more than one nonlinear response surface at a time on a single graph. The first use that we are aware of was in Nelson et al. (2015). In PC-ORD, response surfaces are superimposed on an ordination as an overlay. This enables simultaneous measurement and display of one- and two-dimensional, non-linear community–trait–environment associations.
