)

Arguments

n

A list of 2 positive integers, the number of individuals and organizations.

Q

A list of 2 positive integers, the number of clusters of individuals and organizations.

pi

A vector of probabilities of length Q_O, the mixture parameter for the organizations.

gamma

A Q_I \times Q_O matrix with each column summing to one, the mixture parameters for the individuals

alpha

A list of 2 matrices, a Q_I \times Q_I matrix giving the connectivity probabilities of the individuals and a Q_O \times Q_O matrix giving the connectivity probabilities of the organizations.

directed

A list of 2 logical. Is the individual level a directed network ? Is the inter-organizational level a directed network?

affiliation

The distribution under which the affiliation matrix is simulated in c("uniform", "preferential").

distribution

A list for the distribution of X, only "bernoulli" is implemented.

no_empty_org

A logical with FALSE as default, should every organizations have at least one affiliated individual? Needs to have n_I ≥q n_O.

no_isolated_node

A logical, if TRUE then the network is simulated again until all nodes are connected.

Value

An MLVSBM object, a simulated multilevel network with levels, affiliations and memberships.
