nodemixmeanage-ergmTerm-f93ece12: Average ages of extant ties of specified mixing types

In tergm: Fit, Simulate and Diagnose Models for Network Evolution Based on Exponential-Family Random Graph Models

Average ages of extant ties of specified mixing types

Description

Average ages of extant ties of specified mixing types

Usage

# binary: nodemix.mean.age(attr, b1levels=NULL, b2levels=NULL, levels=NULL,
#                          levels2=NULL, emptyval=0, log=FALSE)

Arguments

attr	a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
b1levels, b2levels, levels, level2	control what statistics are included in the model and the order in which they appear. levels2 apply to all networks; levels applies to unipartite networks; b1levels and b2levels apply to bipartite networks (see Specifying Vertex attributes and Levels (?nodal_attributes) for details)
emptyval	can be used to specify the value returned if the network is empty. A different value may be specified for each mixing type of attr. The length of emptyval should either be 1 (in which case that value is used for every mixing type of attr ) or should be equal to the number of retained mixing types of attr , in which case the i th value in emptyval is used for the i th retained mixing type of attr. This is, technically, an arbitrary value, but it should not have a substantial effect unless a non-negligible fraction of networks at the parameter configuration of interest is empty.
log	logical specifying if mean log age should be returned instead of mean age

Details

This term adds one statistic for each mixing type of attr , equaling the average, over all ties of that mixing type, of the amount of time elapsed since formation.
