plot.varstan: plot methods for varstan models.

Description

Preliminary plot methods for varstan models only valid for univariate time series models. The function prints the fitted values time series, the trace and density plots for the sampled model parameters, or the residuals' posterior mean time series.

Usage

# S3 method for varstan
plot(x, prob = 0.95, ...)

Value

None. Function produces a ggplot2 graph.

Arguments

x

An object of class varstan.

prob

A number \(p \in (0,1)\) indicating the desired probability mass to include in the intervals. The default is to report \(90\%\) intervals (prob=0.9) rather than the traditionally used \(95\%\).

...

Further arguments passed to mcmc_combo.

Examples

# \donttest{
 sf1 = auto.sarima(ts = birth,iter = 500,chains = 1)
 # fitted model
 plot(sf1)
# }
