snap_rank_summary

Ranks year-level snap indices within each retained draw, with rank 1 assigned
to the highest snap index.

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'.

snap_rank_summary function

<dl><dt>fit</dt>
<dd>a <code>lame</code> fit with snap-shift MCMC output, or a
<code>lame_snap_als</code> fit. MCMC fits should be run with retained
snap draws for posterior uncertainty; ALS fits contribute their
<code>snap_prob</code> scores as one score row.</dd>
<dt>actors</dt>
<dd>optional actor names or indices. Default uses every actor on
the selected side.</dd>
<dt>years</dt>
<dd>optional year/period names or indices. Default uses every
period.</dd>
<dt>side</dt>
<dd><code>"u"</code> for sender/row-side snap indicators or <code>"v"</code> for
receiver/column-side indicators.</dd></dl>
