R: Absolute difference in nodal attribute

absdiff-ergmTerm {ergm}

R Documentation

Absolute difference in nodal attribute

This term adds one network statistic to the model equaling the sum of abs(attr[i]-attr[j])^pow for all edges (i,j) in the network.

# binary: absdiff(attr,
#                 pow=1)

# valued: absdiff(attr,
#                 pow=1,
#                 form="sum")

`attr`	quantitative attribute (see Specifying Vertex attributes and Levels (`?nodal_attributes`) for details.)
`pow`	power to which to take the absolute difference
`form`	character how to aggregate tie values in a valued ERGM

ergm versions 3.9.4 and earlier used different arguments for this term. See ergm-options for how to invoke the old behaviour.
