TilburgNetworkGroup/remulate: Package to generate relational event history data

remulate is an R package designed to simulate dynamic temporal networks based on Relational Event Models (REM).

remulate provides a range of features to facilitate the simulation of relational event data:

• Support for Dyadic and Actor-Oriented Models: Simulate both dyadic relational event models and actor-oriented relational event models.
• Rich Collection of Endogenous Statistics: Pre-computed endogenous statistics with multiple normalization and standardization options, along with support for interaction terms.
• Flexible Memory Decay Functions: Includes exponential decay, step-wise decay, and other functions to model the impact of past events on future interactions.
• Custom Risk Sets: Enables simulations with custom risksets where certain actor pairs cannot interact.
• Time-Varying Network Parameters: Allows for variations in network effects over time.
• Time-Varying Nodal Covariates: Allows for variations in node attributes over time.
• Support for Advanced REM Variants:
  • Dyadic latent class relational event models (DLC-REM)
  • Frailty relational event models
  • Relational event block models

The package contains code written in:

• R (>= 4.0.0)
• Rcpp (>= 1.0.4.6) and RcppArmadillo (>= 0.9.860.2.0)
• C++11 (Compiler Version: GCC-8.1.0)

To install the package in R using devtools:

library(devtools)
install_github("TilburgNetworkGroup/remulate")

#load the package
library(remulate)

effects <- ~ baseline(-4) + inertia(0.01) + reciprocity(-0.04) + itp(0.01,scaling="std")

remulateTie(effects, actors = 1:25, time = 20, events = 500, initial = 200)
