#209: check use of set_default_option() --------------------------+------------------------------------------------- Reporter: michel | Owner: Type: bug | Status: new Priority: major | Milestone: 4.3 Component: Core M-files | Version: Keywords: | --------------------------+------------------------------------------------- set_default_option takes an action only if the field name doesn't exist in options_. But, now, most options have a default value set in global_initialization.m, so most of the calls to set_default_option are useless and may, sometimes, not produce the desired results. -- Ticket URL: <https://www.dynare.org/trac/ticket/209> Dynare <http://www.dynare.org> The Dynare project

[Trac] #262: unify names for maxit options

#262: unify names for maxit options ---------------------------------+------------------------------------------ Reporter: michel | Owner: michel Type: enhancement | Status: new Priority: major | Milestone: 5.0 Component: Block decomposition | Version: Keywords: | ---------------------------------+------------------------------------------ Several functions need an optional maximum number of iterations. There is currently no unified name style for these options. Until now, we tried to have exactly the same name for the option in the language and the options_ fieldname. In that case, I wonder if we should not have always maxit in the language and specialized the fieldname with a reference to the function. For example maxit in steady -> options_.solve_maxit -- Ticket URL: <https://www.dynare.org/trac/ticket/262> Dynare <http://www.dynare.org> The Dynare project

It would be more convenient to provide directly these derivatives. -- Ticket URL: <https://www.dynare.org/trac/ticket/160> Dynare <http://www.dynare.org> The Dynare project

In the user's case, we would output: {B^{problem}_{t-1}}^{\rho} -- Ticket URL: <https://www.dynare.org/trac/ticket/263> Dynare <http://www.dynare.org> The Dynare project

[Trac] #276: Add ar-option to estimation command

#276: Add ar-option to estimation command --------------------------+----------------------- Reporter: jpfeifer | Owner: sebastien Type: enhancement | Status: new Priority: minor | Milestone: 5.0 Component: Preprocessor | Version: 4.3.0 Keywords: | --------------------------+----------------------- Currently, the ar-option is only allowed in {{{stoch_simul}}}. Its value then also tranfers to the computation of moments in {{{compute_moments_varendo.m}}}. We should explicitly implement ar in estimation. If specified, it should also trigger the {{{moments_varendo}}} option. This avoids setting {{{options_.ar}}} before the estimation command. Maybe we should split {{{options_.ar}}} into {{{options_.ar}}} for stoch_simul and {{{options_.var_endo_ar}}} for estimation in order for one command not to affect the computations from the other one as is currently the case. -- Ticket URL: <https://www.dynare.org/trac/ticket/276> Dynare <http://www.dynare.org> The Dynare project

[Trac] #267: design an interface for assigning moment/irf contraints (e.g. sign constraints)

#267: design an interface for assigning moment/irf contraints (e.g. sign constraints) -----------------------------------------------------+---------------------- Reporter: ratto | Owner: sebastien Type: feature | Status: new Priority: major | Milestone: 5.0 Component: Identification and sensitivity analysis | Version: Keywords: | -----------------------------------------------------+---------------------- Currently there is no way of setting a set of constraints to irfs or moments of DSGE model to feed to some calibration procedure like Monte Carlo filtering in the sensitivity analysis toolbox. Indeed the threshold_redform option in sensitivity analysis would only allow to set, e.g., the SAME sign constraint to a set of irfs, which is not very handy. So, we may think to the following syntax for sign constraints in moments: moment_calibration; y, y(-1), +; [i.e. auto-correlation with 1 lag] c, g(-3), +; [i.e. auto-correlation with generic lags] i, g, -; [i.e. cross-correlation, contemporaneous] end; for irfs [y c i are endogenous, em eg are exogenous shocks]: irf_calibration; y, em, -; c, eg, +; i, eg, -; end; or the following for more detailed numeric boundaries, in principle mixed with simple sign constraints moment_calibration; y, y(-1), [0.5 1]; [auto-correlation with 1 lag] c, g(-3), +; [auto-correlation with generic lags] i, g, [-1, -0.5]; [cross-correlation, contemporaneous] end; irf_calibration; y, em, [-0.01 0]; c, eg, [0 0.02]; i, eg, -; end; The sign constraint can also be defined using [0 inf] for + [-inf 0] for - -- Ticket URL: <https://www.dynare.org/trac/ticket/267> Dynare <http://www.dynare.org> The Dynare project

However, it would be handful to allow inf as input, e.g. if one wants to filter positive numbers in an irf, one would like to use a syntax [0 inf]. -- Ticket URL: <https://www.dynare.org/trac/ticket/266> Dynare <http://www.dynare.org> The Dynare project

Bug in stochastic_solvers for bytecode at order 2
by Johannes Pfeifer 16 Nov '12

16 Nov '12

Dear all, there is a bug in stochastic_solvers for bytecode at order 2 in 4.3.1 and master. The variable hessian1 needed for dr = dyn_second_order_solver(jacobia_,hessian1,dr,M_,... options_.threads.kronecker.A_times_B_kronecker_C,... options_.threads.kronecker.sparse_hessian_times_B_kronecker_C); is not set in this case. A sample mod-file, usable as a unit test is attached. Best, Johannes -- Johannes Pfeifer Haußerstr. 29 72076 Tübingen Tel.: +49-(0)7071-6396184 Mobil.: +49-(0)170-6936820 Germany
