logLik.ame_als

The fast estimator minimises a (working-response) least-squares objective,
not a family likelihood, so it has no log-likelihood and <code>AIC</code> / <code>BIC</code>
are undefined. Calling <code><a href="/link/logLik()?package=lame&version=1.3.4" data-mini-rdoc="lame::logLik()">logLik()</a></code> raises an informative error rather
than returning a misleading number.

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'.
