nobs.ame

nobs.lame

Number of finite (non-missing) cells in <code>Y</code>, summed over time slices
for longitudinal fits. Useful as a denominator for sample-size reporting
and as the basis for AIC/BIC if you also have a log-likelihood
(which <code>ame()</code> / <code>lame()</code> do not directly expose; see
<code>logLik.ame</code>).

Additive and multiplicative effects models for both cross-sectional and longitudinal network analysis. The package provides two main functions: ame() for cross-sectional networks and lame() for longitudinal networks. It supports square and rectangular network structures. Key features include: (1) Cross-sectional network analysis via ame() with support for binary, continuous, ordinal, and count data; (2) Longitudinal network analysis via lame() with additive sender/receiver and multiplicative latent-factor effects that can evolve over time through AR(1) processes (Sewell and Chen (2015) <doi:10.1080/01621459.2014.988214>; Durante and Dunson (2014) <doi:10.1093/biomet/asu040>); (3) Handling of changing actor compositions across time periods in longitudinal models; (4) Performance improvements through C++ implementations via 'Rcpp' and 'RcppArmadillo'.
