orwg: Odds ratio of existence of within-group ties

In netseg: Measures of Network Segregation and Homophily

Odds ratio of existence of within-group ties

Description

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.

Usage

orwg(object, ...)

## S3 method for class 'table'
orwg(object, ...)

## S3 method for class 'igraph'
orwg(object, vattr, ...)

## Default S3 method:
orwg(object, ...)

Arguments

object	R object, see Details for available methods
...	other arguments passed to/from other methods
vattr	character scalar or any vector, name of the vertex attribute or the attribute itself (as a vector)

Details

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.

Value

Numeric value of the measure.
