FlexReg (version 1.3.1)

plot.flexreg_postpred: Plot Method for `flexreg_postpred` objects

Description

Method for an object of class `flexreg_postpred` containing the simulated posterior predictive distribution, usually the result of posterior_predict function. 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 continuous or discrete 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 continuous or discrete 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)
}
