mm-ergmTerm {ergm}

Mixing matrix cells and margins

Description

attrs is the rows of the mixing matrix and whose RHS gives that for its columns. 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.

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

form

character how to aggregate tie values in a valued ERGM
