Temporal (and Cross-Sectional) Network Autocorrelation Models (TNAM).
The package uses maximum pseudolikelihood for estimation, which is likely biased. Consider using the multiparametric spatio-temporal autoregressive (M-STAR) model instead if you have temporal data. If you have a cross-sectional dataset, consider using the BANAM package. The tnam package is archived until better estimation routines have been implemented, but there are currently no plans for this.
