set_free_par: Setting free parameters' values

In gEcon: General Equilibrium Economic Modelling Language and Solution Framework (gEcon)

Description

The set_free_par function allows to set values of free parameters occurring in a gecon_model class object.

Usage

set_free_par(model, free_par = NULL, reset = FALSE, warnings = TRUE)

Arguments

model	an object of gecon_model class.
free_par	a named list or a vector of parameters.
reset	a logical value, if TRUE, the function allows to reset free parameters to values from the .gcn file.
warnings	logical, if TRUE, a warning is displayed whenever the default parameter value (specified in the .gcn file) is overwritten.

Value

An updated object of gecon_model class representing the model. If the reset option is set to TRUE, the model's parameters will be set back to values from the .gcn file. Generic functions such as print and summary allow to show model elements. The get_par_values function returns parameters' values currently in use.

Examples

# copy the example to the current working directory
file.copy(from = file.path(system.file("examples", package = "gEcon"),
          "rbc.gcn"), to = getwd())

# make and load the model
rbc <- make_model("rbc.gcn")

# set free parameters' values different from those in the .gcn file
rbc <- set_free_par(rbc, free_par = list(beta = 0.98, delta = 0.01))
rbc <- steady_state(rbc, options = list(method = "Broyden",
                                        global = "gline"))
get_ss_values(rbc)

# reset values to .gcn file values
rbc <- set_free_par(rbc, reset = TRUE)
rbc <- steady_state(rbc)
get_ss_values(rbc)
