In christophergandrud/zibHelpers: Helper functions for handling results from Bayesian Zero-Inflated Beta Regressions in R

Description

Function to plot parameter posteriors from Zero-inflated Beta Regressions

Usage

zibPlot(obj, iter, variable_names = NULL, xlab = "\nCoef. Estimates",
  title = "")

Arguments

obj	model object from zoib where one.inflation = FALSE and joint = FALSE.
iter	integer. The number of iterations.
variable_names	character vector of variable names. Must be in the same order and the same length as variables enterd into the zoib formula.
xlab	character string x-axis label.
title	character string title for the plot

Value

a ggplot2 plot

Examples

## Not run: 
Load packages
library(zoib)
library(zibHelpers)

# Run example of clustered zero-inflated beta regression from
# Liu and Kong (under review, 12-14)

# Load data
data("AlcoholUse", package = "zoib")
AlcoholUse$Grade <- as.factor(AlcoholUse$Grade)

nIter = 50 # Number of iterations, including burn-in

# Estimate
Out <- zoib(Percentage ~ Grade + Days + Gender|1|Grade + Days + Gender|1,
            data = AlcoholUse, random = 1, EUID = AlcoholUse$County,
            zero.inflation = TRUE, one.inflation = FALSE, joint = FALSE,
            n.iter = nIter)

# Plot the posterior summary
zibPlot(Out, iter = nIter)

## End(Not run)
