build_exchangeable_matrix: Build an exchangeable matrix of sparseMatrix class

Description

Build an exchangeable matrix of sparseMatrix class

Usage

build_exchangeable_matrix(n, phi, directed = TRUE, dyads = NULL)

Arguments

n

Number of actors in the network, scalar numeric.

phi

Appropriate-length vector of parameters, must be length 5 or 6 for directed=TRUE or length 2 or 3 for directed=FALSE.

directed

Optional logical indicator of whether input data is for a directed network, default is TRUE. Undirected data format is lower triangle of adjacencey matrix.

dyads

Optional numeric vector of dyads to subset the matrix to.

Value

out

Exchangeable matrix.

Details

This function builds a covariance matrix in the exchangeable class from the vector of parameters input. See Marrs et.al. (2017).
