function DynareOutput = simul_backward_model(varargin)
|
|
|
|
% Simulates a stochastic backward looking model (with arbitrary precision).
|
|
%
|
|
% INPUTS
|
|
% - initialconditions [double] n*1 vector, initial conditions for the endogenous variables.
|
|
% - samplesize [integer] scalar, number of periods for the simulation.
|
|
% - DynareOptions [struct] Dynare's options_ global structure.
|
|
% - DynareModel [struct] Dynare's M_ global structure.
|
|
% - DynareOutput [struct] Dynare's oo_ global structure.
|
|
% - innovations [double] T*q matrix, innovations to be used for the simulation.
|
|
%
|
|
% OUTPUTS
|
|
% - DynareOutput [struct] Dynare's oo_ global structure.
|
|
%
|
|
% REMARKS
|
|
% [1] The innovations used for the simulation are saved in DynareOutput.exo_simul, and the resulting paths for the endogenous
|
|
% variables are saved in DynareOutput.endo_simul.
|
|
% [2] The last input argument is not mandatory. If absent we use random draws and rescale them with the informations provided
|
|
% through the shocks block.
|
|
% [3] If the first input argument is empty, the endogenous variables are initialized with 0, or if available with the informations
|
|
% provided thrtough the histval block.
