Computes the significance of more complex model against a simpler model by means of a likelihood ratio test.

nr.significance(mod0 = NULL, mod1, adj = NULL)

## Arguments

mod0 null nrm model (optional). defaults to the scm model. alternative nrm model, the model to test adjacency matrix for which performing the test. (optional) defaults to the matrix used for mod1.

## Value

p-value of the lr test mod0 vs mod1
