gecon_var_info-class: 'gecon_var_info' class

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

Description

The class storing information about variables selected by the user.

Slots

r_object_name:

a character string. The name of an R object of gecon_model class storing the model from which the information about variables comes from.

variables:

a character vector of selected variables' names.

is_stochastic:

logical. Set to TRUE, if the model, based on which the info was generated, has stochastic shocks.

is_dynamic:

logical. Set to TRUE, if the model, based on which the info was generated, has any lead or lagged variables.

ss_solved:

logical. Set to TRUE, if the steady state/equilibrium of the model has been found.

re_solved:

logical. Set to TRUE, if the model, based on which the info was generated, has been solved.

corr_computed:

logical. Set to TRUE, if correlations and other statistics of variables have been computed.

ss_val:

a vector of the steady-state (dynamic models) or equilibrium (static models) values of selected variables. If the steady state has not been computed, the vector contains initial values of variables.

state:

a logical vector of length equal to the number of selected variables. A TRUE entry denotes that a corresponding variable is a state variable.

state_var_impact:

the rows of the matrices P and R of state space representation corresponding to selected variables.

shock_impact:

the rows of the matrices Q and S of state space representation corresponding to selected variables.

std_dev_val:

a numeric vector of standard deviations of selected variables.

loglin_flag:

a logical vector of length equal to the number of selected variables. A TRUE entry denotes that a corresponding variable was log-linearised before solving the model.

cr:

a matrix containing the correlations of selected variables with all model variables.

incid_mat:

an object of Matrix class representing the mapping of variables to model equations and calibrating equations.

Methods

print

signature(x = "gecon_var_info"): Prints all the available information (values, statistics, incidence matrix, etc.) about the variables, which were selected when creating a gecon_var_info-class object.

show

signature(object = "gecon_var_info"): Prints all the available information (values, statistics, incidence matrix, etc.) about the variables, which were selected when creating a gecon_var_info-class object.

summary

signature(object = "gecon_var_info"): Prints all the available information (values, statistics, incidence matrix, etc.) about the variables, which were selected when creating a gecon_var_info-class object.

See Also

var_info creates an object of gecon_var_info class. gecon_shock_info-class and gecon_par_info-class are similar classes storing the information about shocks and parameters, respectively.

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")

# compute the steady state
rbc <- steady_state(rbc)
rbc <- solve_pert(rbc)
rbc_var_info <- var_info(rbc, all = TRUE)
print(rbc_var_info)
summary(rbc_var_info)
show(rbc_var_info)
