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,
