Plotting the impact of the assumed sampling correlation on the overall average effect size estimate

Source: R/rho_impact.R
plot_rho_impact.Rd

Creates a plot showing the impact on the assumed sampling correlation (\(\rho\)) on the overall average effect size and the variance estimation.

Usage

plot_rho_impact(
  data,
  rho_used,
  prediction_interval = FALSE,
  ylab_beta = NULL,
  var_breaks = NULL
)

Arguments

data

Data/object for which the plot should be made.

rho_used

Numerical value indicating the (assumed) sampling correlation used to fit the main CHE-RVE model.

prediction_interval

Logical indicting whether a plot showing the impact of the sampling correlation on the prediction interval estimation.

ylab_beta

Optional character with the y-axis label for the overall mean effect plot

var_breaks

Optional vector setting the y-axis breaks for the variance plot.

Value

A ggplot object
