get_pert_solution {gEcon} | R Documentation |
The get_pert_solution
function prints and returns the recursive laws of motion of the model's variables.
# getting recursive laws of motion get_pert_solution(model, to_tex = FALSE, silent = FALSE)
model |
an object of |
to_tex |
a logical value. If TRUE, the output is written to a .tex file. The default value is FALSE. |
silent |
a logical value. If TRUE, console output is suppressed. The default value is FALSE. |
A list of P
, Q
, R
, S
matrices
(P
and R
only in case of a deterministic model),
a vector of variables' steady-state values (ss_val
),
a vector of flags indicating which variables were log-linearised (loglin
),
and a vector of indices of state variables (state_ind
).
P
and Q
matrices describe the impact of lagged state variables
and current values of shocks on current values of state variables.
R
and S
matrices describe the impact of lagged state variables
and current values of shocks on current values of non-state (jump) variables.
