plot.Forecasts {bsvars}

Plots fitted values of dependent variables

Description

Plots of fitted values of dependent variables including their median and percentiles.

Usage

## S3 method for class 'Forecasts'
plot(
  x,
  probability = 0.9,
  data_in_plot = 1,
  col = "#ff69b4",
  main,
  xlab,
  mar.multi = c(1, 4.6, 0, 2.1),
  oma.multi = c(6, 0, 5, 0),
  ...
)

Arguments

x

an object of class Forecasts obtained using the forecast() function containing posterior draws of fitted values of dependent variables.

probability

a parameter determining the interval to be plotted. The interval stretches from the 0.5 * (1 - probability) to 1 - 0.5 * (1 - probability) percentile of the posterior distribution.

data_in_plot

a fraction value in the range (0, 1) determining how many of the last observations in the data should be plotted with the forecasts.

col

a colour of the plot line and the ribbon

main

an alternative main title for the plot

xlab

an alternative x-axis label for the plot

mar.multi

the default mar argument setting in graphics::par. Modify with care!

oma.multi

the default oma argument setting in graphics::par. Modify with care!

...

additional arguments affecting the summary produced.

posterior      = estimate(burn_in, 20, thin = 1)      # estimate the model

# compute forecasts
fore            = forecast(posterior, horizon = 4)
plot(fore)                                            # plot forecasts
