Visualizing the random effect estimates using ggplot2

Using this function, you can create plots of the random effect estimates from fitted random effects models. To make the plots, we rely on the ggplot2 package.

plotRE(
  obj,
  levelRE = c("all", "first", "second"),
  colour = "black",
  plot = TRUE
)

Arguments

obj

an object of type hierCredibility, hierCredGLM or hierCredTweedie

levelRE

indicates which hierarchical level has to be used. "all" plots both levels in the hierarchy, "first" the first level in the hierarchy and "second" the second level.

colour

colour for geom_point

plot

logical indicating if the ggplot objects have to be plotted.

Value

a list with ggplot objects.

Examples

# \donttest{
fitHGLM <- hierCredGLM(Y ~ area + gender + (1 | VehicleType / VehicleBody), dataCar, weights = w)
plotRE(fitHGLM)
