FlexReg (version 1.2)

plot.flexreg_postpred: Posterior Predictives Plot

Description

Method for plotting the simulated posterior predictive distribution from an object of class `flexreg_postpred`. The plot shows the posterior predictive interval for each statistical unit. Additionally, the mean of the posterior predictives and the values of the observed response (either \(y\) or \(y/n\) for bounded or binomial responses, respectively) can be added.

Usage

# S3 method for flexreg_postpred
plot(x, prob = 0.9, p_mean = F, response = NULL, ...)

Arguments

x

an object of class `flexreg_postpred` containing the simulated posterior predictives, usually the result of posterior_predict.

prob

the interval probability for the posterior predictives (default is 0.9).

p_mean

a logical value indicating whether the posterior predictives' mean should be plotted.

response

a numerical vector containing the response (either \(y\) or \(y/n\) for bounded or binomial responses, respectively) to be added to the plot. If NULL, observed values are not plotted.

...

additional arguments. Currently not used.

Examples

if (FALSE) {
data("Reading")
FB <- flexreg(accuracy ~ iq, data = Reading)
pp <- posterior_predict(FB)
plot(pp)
}
