Plot JVN model results — plot.jvn_model • reviser

Plot filtered or smoothed estimates for a selected state from a fitted jvn_model.

Usage

# S3 method for class 'jvn_model'
plot(x, state = "true_lag_0", type = "filtered", ...)

Arguments

x: An object of class jvn_model.
state: Character scalar giving the state to visualize. Defaults to "true_lag_0".
type: Character scalar indicating whether "filtered" or "smoothed" estimates should be plotted.
...: Additional arguments passed to plot.revision_model().

Value

A ggplot2 object.

Details

This method requires x$states to be available. If the model was fitted with solver_options$return_states = FALSE, plotting is not possible.
