The Formation Operator Term

Description

The Formation Operator Term

Usage

# binary: Form(
#           formula,
#           lm = ~1,
#           subset = TRUE,
#           weights = 1,
#           contrasts = NULL,
#           offset = 0,
#           label = NULL
#         )

Arguments

formula

a one-sided ergm()-style formula with the terms to be evaluated

lm, subset, weights, contrasts, offset, label

NetSeries() LHS only arguments to specify time-varying parameters. See N() term operator in the ergm.multi for details. lm formula may reference .Time for the network's time index, .TimeID for the its index in the network series (where the initial network is 1 and the first modelled network is 2), and .TimeDelta for the time elapsed between the network and the immediately previous network in the series.

Details

This term accepts a model formula and produces the corresponding model for the post-formation network: effectively a network containing both previous time step's ties and ties just formed, the union of the previous and current network. This is the equivalent of the old-style formation model.
