mm-ergmTerm-0264ed3f: Mixing matrix cells and margins

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

Mixing matrix cells and margins

Description

attrs is the rows of the mixing matrix and whose RHS gives that for its columns (which may be different). A one-sided formula (e.g., ~A ) is symmetrized (e.g., A~A ). A two-sided formula with a dot on one side calculates the margins of the mixing matrix, analogously to nodefactor , with A~. calculating the row/sender/b1 margins and .~A calculating the column/receiver/b2 margins. If row and column attributes are the same and the network is undirected, only the cells at or above the diagonal (where \text{row} \le \text{column}) will be calculated.

Usage

# binary: mm(attrs, levels=NULL, levels2=-1)

# valued: mm(attrs, levels=NULL, levels2=-1, form="sum")

Arguments

attrs	a two-sided formula whose LHS gives the attribute or attribute function (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.) for the rows of the mixing matrix and whose RHS gives for its columns. A one-sided formula (e.g., ~A) is symmetrized (e.g., A~A)
levels	subset of rows and columns to be used. (See Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
levels2	which specific cells of the matrix to include; ?nodal_attributes for details
form	character how to aggregate tie values in a valued ERGM
