Description

Creates a plot for the long-run relationship in comparison with the dependent variable, and the fitted values of the model. This is a basic ggplot with a few customizable parameters.

Usage

plot_lr(
  object,
  coint_eq,
  facets = FALSE,
  show_fitted = FALSE,
  show.legend = FALSE,
  xlab = "Time",
  ...
)

Arguments

object

An object of class 'ardl'.

coint_eq

The objected returned from coint_eq.

facets

A logical indicating whether the long-run relationship appears in a separate plot. Default is FALSE.

show_fitted

A logical indicating whether the fitted values are shown. Default is FALSE.

Examples

ardl_3132 <- ardl(LRM ~ LRY + IBO + IDE, data = denmark, order = c(3,1,3,2))
ce2 <- coint_eq(ardl_3132, case = 2)

plot_lr(ardl_3132, coint_eq = ce2)

## Compare fitted values and place long-run relationship separately ----

ce3 <- coint_eq(ardl_3132, case = 3)
plot_lr(ardl_3132, coint_eq = ce3, facets = TRUE, show_fitted = TRUE,
        show.legend = TRUE)
