This workshop is intended for participants who have experience in working with RSiena. Topics treated will be the following – all in the framework of modelling network panel data using the RSiena package 1. Parameter interpretation: semi-standardized parameters; entropy-based approach to explained variation. 2. Score-type tests. 3. Problems with convergence: various kinds. 4. Elementary effects and contextual effects. 5. Multivariate networks: cross-network effects; with attention to the associated hierarchy requirements. 6. Two-mode networks, and their co-evolution with one-mode networks. 7. Some effects that are little known, but which may be useful for analyzing two-mode networks. 8. If time allows: Non-directed networks. 9. If time allows: Valued networks (two kinds: networks with weak and strong ties; signed networks). SIENA website: http://www.stats.ox.ac.uk/~snijders/siena
