We are pleased to announce the release of Dynare 4.5.7.
This is a bugfix release.
This release is compatible with MATLAB versions 7.5 (R2007b) to 9.4 (R2018b)
and with GNU/Octave version 4.4.1.
## Bug Fixes
Here is a list of the problems identified in version 4.5.6 and that have been
fixed in version 4.5.7:
- The mex-file conducting the QZ decomposition erroneously applied
the `qz_criterium` to the square absolute value of eigenvalues
instead of the absolute value itself (as done in mjdgges.m and the
AIM solver).
- In pathological cases, `mode_compute=5` (`newrat`) might enter an
infinite loop.
- `discretionary_policy` might erroneously state that the derivatives
of the objective function are non-zero if there are NaN present.
- Dynare++, when conducting the QZ decomposition, erroneously applied
the `qz_criterium` to the square absolute value of eigenvalues
instead of the absolute value itself.
- Dynare++: IRFs were incorrectly computed.
- `dynare_sensitivity` did not display the figures of
`irf_calibration`, it only stored them on the disk.
- Scatter plots generated by `dynare_sensitivity` did not correctly
display LaTeX names.
- Parameter updating via steady state files did not correctly work in
case of using [static]/[dynamic] equation tags.
- Memory leaks in `k_order_pert` (used by higher order stochastic
simulations) could lead to crashes.
- Predetermined variables were not properly set when used in model
local variables.
- Posterior moment computation did not correctly update the
covariance matrix of exogenous shocks during posterior sampling.
- Dynare was crashing with a cryptic message if a non estimated
parameter was initialized in the `estimated_params_init` block.
- The `forecast` command crashed if the model was declared as linear
and contained deterministic exogenous variables.
- Block decomposition is broken when used in conjunction with
`varexo_det`.
- The model was not correctly specified when `identification` was run
without another stochastic command in the `.mod` file
(e.g. `estimation`, `stoch_simul`, etc.).
- Realtime annualized shock decompositions added the wrong steady state
value.
- `mh_recover` option crashed when using slice sampler.
- x-axis values in plots of moment restrictions were wrong for
autocovariances.
