In NetMiner3, Observed values and statistics result from Triad Census
simulation are presented. For 16 triad isomorphism classes and significance
test, observed, expected, standard deviation, standard error and variance
are reported.

For significance test, algorithm computes triad census from randomly
generated matrices having same row marginal totals, column marginal totals,
and optionally dyad census (with given sociomatrix) and it reports that.

Random generated matrix is two.

- MCMC[U(Xi+, X+j)]: Generate new matrices whose row marginal totals and
column totals are same to input matrix. Thus, nodes' in-degree and
out-degree of new matrices are same to those of original matrix. The
analyzed result of new matrices is used for comparing with the result of
original matrix.
- MCMC[U(Xi+, X+j, MAN)] : Generate matrices having upper condition and same
dyad census with original matrix. The analyzed result of new matrices is
used for comparing with the result of original matrix.

 

Thanks,

Dear List,

Please is there an available program that calculates the mean and variance
of the triad census vector for U|MAN random graph models?

 

Regards,
