R: Absolute difference in nodal attribute

absdiff-ergmTerm {ergm} | R Documentation

## Absolute difference in nodal attribute

### Description

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.

### Usage

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

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

### Arguments

`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

### Note

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