Do correlation/do partial correlation: GraphVar enables you to compute correlations
between specific graph metrics (see “Network Calculations panel”) and user defined
variables (see “Variables”). GraphVar offers the selection between a regular correlation
(pearson correlation) and a partial correlational analysis. When you select the
“Do partial correlation” checkbox, you are demanded to select the respective variables in the selection
box below that you want to control for. Selection of multiple variables for correlation and as
covariates is possible. If you want to do non-parametric testing of the correlation strenght (r)
please refer to the “Test against random networks (Correlation)” option.

It is also possible to perform correlational analyses on the “raw” correlation/association matrices
(i.e., association-matrix based statistics, where no graph topological measures are
involved). For this feature please refer to the “Raw Matrix –Correlation” panel.
