NSBM.Gen | R Documentation |
Generates networks from nomination stochastic block model for community structure in edge nomination procedures, proposed in Li et. al. (2020)
NSBM.Gen( n, K, avg.d,beta,theta.low=0.1,
theta.p=0.2,lambda.scale=0.2,lambda.exp=FALSE)
n |
size of network |
K |
number of communities |
avg.d |
expected average degree of the resuling network (after edge nomination) |
beta |
the out-in ratio of the original SBM |
theta.low |
the lower value of theta's. The theta's are generated as two-point mass at theta.low and 1. |
theta.p |
proportion of lower value of theta's |
lambda.scale |
standard deviation of the lambda (before the exponential, see lambda.exp) |
lambda.exp |
If TRUE, lambda is generated as exponential of uniformation random randomes. Otherwise, they are normally distributed. |
A list of
A |
the generated network adjacency matrix |
g |
community membership |
P |
probability matrix of the orignal SBM network |
P.tilde |
probability matrix of the observed network after nomination |
B |
B parameter |
lambda |
lambda parameter |
theta |
theta parameter |
