The R software package remstats was developed for efficient computation of statistics for
analyzing relational event history data with relational event models (REMs). The software
package includes a wide range of endogenous and exogenous statistics for a tie-oriented REM
(Butts, 2008) or actor-oriented REM (DyNAM, Stadtfeld & Block, 2017). It can handle directed
and undirected events and allows for REMs that consider event types in the dependent
variable. The resulting object can be used with the R software packages remstimate or
relevent (Butts, 2008) to obtain estimates for the model parameters. The package can be retrieved from GitHub.
