Odds ratio for connected, as opposed to disconnected, dyads depending whether it is between- or within-group, i.e. how much more likely the dyad will be connected if it is within-group.
orwg(object, ...)# S3 method for table
orwg(object, ...)
# S3 method for igraph
orwg(object, vattr, ...)
# S3 method for default
orwg(object, ...)
Numeric value of the measure.
R object, see Details for available methods
other arguments passed to/from other methods
character scalar or any vector, name of the vertex attribute or the attribute itself (as a vector)
The measure takes values, like all odds ratios, from (0; Inf).
If object is a table it is interpreted as a mixing matrix.
Two-dimensional table is interpreted as a contact layer. Three-dimensional
table is interpreted as a full mixing matrix \(m_{ghy}\)
cross-classyfying all dyads, in which \(g\) and \(h\) correspond to
group membership of ego and alter respectively. Layers \(y=1\) and
\(y=2\) are assumed to be non-contact and contact layers respectively.
If object is of class "igraph" it is required to supply vattr
with the name of the vertex attribute to calculate intermediate mixing
matrix.
