bip.degdist.check: Check Degree Distribution for Bipartite Target Statistics

Description

This function checks for consistency in the degree distributions between the two modes in a bipartite network, and if balance is present returns the implied network statistics for use in a ERGM.

Usage

bip.degdist.check(num.m1, num.m2, deg.dist.m1, deg.dist.m2)

Arguments

num.m1

number of vertices in mode 1.

num.m2

number of vertices in mode 2.

deg.dist.m1

vector with fractional degree distribution for mode 1.

deg.dist.m2

vector with fractional degree distribution for mode 2.

Details

This function outputs the number of nodes of degree 0 to m, where m is the length of a fractional degree distribution vector, given that vector and the size of the mode. This utility is used to check for balance in implied degree given that fractional distribution within bipartite network simulations, in which the degree-contrained counts must match across modes.

Examples

# An imbalanced distribution
bip.degdist.check(num.m1 = 500, num.m2 = 500,
                  deg.dist.m1 = c(0.40, 0.55, 0.03, 0.02),
                  deg.dist.m2 = c(0.48, 0.41, 0.08, 0.03))

# A balanced distribution
targets <- bip.degdist.check(num.m1 = 500, num.m2 = 500,
                  deg.dist.m1 = c(0.40, 0.55, 0.04, 0.01),
                  deg.dist.m2 = c(0.48, 0.41, 0.08, 0.03))
