remstats

Computes Statistics for Relational Event History Data

The `remstats` package is designed to compute a variety of statistics for relational event models. Relational event modeling approaches enable researchers to investigate both exogenous and endogenous factors influencing the evolution of a time-ordered sequence of relational events. These models are categorized into tie-oriented models, where the probability of a dyad interacting next is modeled in a single step (e.g., see Butts, 2008), and actor-oriented models, which first model the probability of a sender initiating an interaction and subsequently the probability of the senders' choice of receiver (e.g., see Stadtfeld & Block, 2017). The `remstats` package is designed to compute a variety of statistics that characterize exogenous and endogenous influences on the event stream for both types of models.

The package is part of a bundle of R-packages developed by researchers from Tilburg University intended to aid applied researchers in the application of relational event modeling. For preparing the relational event history, remstats assumes the prior application of remify::remify() (available on CRAN or on Github). Model estimation can subsequently be executed using remstimate (available on CRAN or on GitHub).

Installation

To install the package in R from CRAN, use:

install.packages("remstats")
library(remstats)

Workflow example

# Load example data
data(history)
data(info)

# Define effects
effects <- ~ 1 + send("extraversion", info) + inertia()

# Prepare event history with the 'remify package' 
# Install with install.packages("remify")
rehObject <- remify::remify(edgelist = history, model = "tie")

# Compute statistics
statsObject <- remstats(reh = rehObject, tie_effects = effects)

# Estimate model parameters with the 'remstimate' package
# Install with install.packages("remstimate")
fit <- remstimate::remstimate(reh = rehObject, stats = statsObject,
    method = "MLE", timing = "interval")
