#135: Improve display of decision rules with EXPECTATION operator --------------------------+------------------------------------------------- Reporter: sebastien | Owner: sebastien Type: enhancement | Status: new Priority: minor | Milestone: 4.3 Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- Currently, if the user inputs EXPECTATION(-1)(some_expr) in her model, then a new aux variable is created, and this var is a state var, which appears in the decision rules as EXPECTATION(-1)(...) (with the dots instead of the expression). This is not very informative. Displaying the full expression would require to add a new writeOutput method in the preprocessor. And for something like EXPECTATION(-2)(some_expr), it is even worse, because there are 2 aux vars: one for the operator, and the second one which appears when removing lags of 2. It is the latter which appears in stoch_simul. Fixing this requires to fix the orig_endo field of M_.aux_vars in that case. -- Ticket URL: <https://www.dynare.org/trac/ticket/135> Dynare <http://www.dynare.org> The Dynare project

#86: check matrix power used in forecast --------------------------+------------------------------------------------- Reporter: michel | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Core M-files | Version: Keywords: | --------------------------+------------------------------------------------- taking large matrix power in forecast step of the Kalman smoother routines is expensive, but probably more accurate than recursive multiplications. - investigate more accuracy issue - factorise matrix decomposition for matrix power -- Ticket URL: <https://www.dynare.org/trac/ticket/86> Dynare <http://www.dynare.org> The Dynare project

[Trac] #83: persistent variables must be cleared at the beginning of a Dynare run

#83: persistent variables must be cleared at the beginning of a Dynare run --------------------------+------------------------------------------------- Reporter: michel | Owner: michel Type: bug | Status: new Priority: minor | Milestone: Component: Core M-files | Version: 4.1.0 Keywords: | --------------------------+------------------------------------------------- persistent variables in *.m files trigger hard to understand errors if the user run successively two different *.mod files with 'noclearall' option. Whenever a function uses persistent variables, there should be an explicit initialize option and not rely on empty persistent variables as, for example, priordens.m currently does. -- Ticket URL: <https://www.dynare.org/trac/ticket/83> Dynare <http://www.dynare.org> The Dynare project

[Trac] #172: improve derivation engine for derivatives of STEADY_STATE wrt parameters

#172: improve derivation engine for derivatives of STEADY_STATE wrt parameters --------------------------+------------------------------------------------- Reporter: sebastien | Owner: sebastien Type: enhancement | Status: new Priority: major | Milestone: 4.3 Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- Currently the derivatives of STEADY_STATE operator wrt to parameters are not handled in an efficient way, because the preprocessor does not exploit the a priori information for identifying null derivatives. This results in huge files for not so complicated models, which cannot be exploited by identification routines. The proposal is to implement an algorithm in the preprocessor for identifying null derivatives ex ante: - Create a non-directed graph whose nodes are the endogenous variables and the parameters - For each pair of nodes, add an edge between the two if there is an equation in the static model containing both corresponding symbols (endogenous/parameters) - For each endogenous, its derivative wrt a parameter is always zero if there is no path between the node representing the endogenous and the node representing the parameter. -- Ticket URL: <https://www.dynare.org/trac/ticket/172> Dynare <http://www.dynare.org> The Dynare project
