fergm_beta_traceplot function

Plot traceplots for model terms.

Plot traceplots for model terms.

This function takes a fergm object and plots the time series of each chain per model term using ggplot2.

fergm_beta_traceplot(fergm.fit = NULL, custom_var_names = NULL)

Arguments

  • fergm.fit: A model object returned by the fergm function. Must be specified.
  • custom_var_names: A vector of custom variable names used in presentation that match the order of the form object passed to fergm. If not provided, defaults to names inherited by fergm.fit.

Returns

This prints a ggplot2 traceplot for the effects of interest.

Examples

# load example data
data("ergm.fit")
data("fergm.fit")
data("mesa")
# Use rstan's built in traceplot function
trace <- rstan::traceplot(fergm.fit$stan.fit, pars = "beta")
trace

# We have our own version that includes variable names and tidies it up a bit
fergm_beta_traceplot(fergm.fit,
                    custom_var_names =  c("Edges", "Sex Homophily",
                    "Grade Homophily", "Race Homophily", "GWESP", "Alternating K-Stars"))
