#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

But at orders 2 and above, the equivalence does not hold. -- Ticket URL: <https://www.dynare.org/trac/ticket/115> Dynare <http://www.dynare.org> The Dynare project

#233: Smoother on calibrated models -----------------------+---------------------------------------------------- Reporter: sebastien | Owner: Type: feature | Status: new Priority: major | Milestone: 4.3 Component: General | Version: Keywords: | -----------------------+---------------------------------------------------- Add the possibility of running the smoother on a calibrated model. It may be already possible to do so, by giving no estimated_params and then running estimation with mode_compute=0. If this indeed works, we need to add an interface by creating a new MOD-file command that would output the right call to estimation. -- Ticket URL: <https://www.dynare.org/trac/ticket/233> Dynare <http://www.dynare.org> The Dynare project

[Trac] #194: Clarify Slicot licensing terms

#194: Clarify Slicot licensing terms ----------------------------+----------------------------------------------- Reporter: sebastien | Owner: george Type: bug | Status: new Priority: critical | Milestone: Component: Estimation DLL | Version: Keywords: | ----------------------------+----------------------------------------------- Currently Dynare (unstable) distributes its own copy of libslicot (www.slicot.org). It is used in the Kalman Steady State DLL (at least). As of July 15, 2011, it is no longer possible to download libslicot from its website. It says that the library is currently undergoing a relicensing. We need to clarify this with Slicot authors to see if we can continue distributing it with Dynare. -- Ticket URL: <https://www.dynare.org/trac/ticket/194> Dynare <http://www.dynare.org> The Dynare project
