Release History
0.90.1 (2012-9-27)
- Differentiation in the variable substitution section is now “smarter” and understands inter-temporal differentiation with special @DISCOUNT variable
- Implemented the Christiano-Fitzgerald asymmetric band-pass filter to extract stationary cycle from simulated data.
- Eliminated some small bugs in parser module.
- Made new stats.VAR and stats.FAVAR experimentally available, but this is not documented yet !
- Also included the Fred API with the PyMacLab package to download data from the St. Louis Fed.
- The DSGE model filepath handles have been split into “models.stable.xmodel”, “models.development.xmodel” and “models.testing.xmodel”
- The updater methods for dynamic runtime changes to DSGE models to are pretty much complete now.
- Have started adding more API documentation to PyMacLab Sphinx docs.
- The example/test files have been considerably updated. But need to implement Python nose cases next.
- Updated documentation substantially.
- TODO: More DSGE models have to be added and existing ones modified.
- TODO: The documentation is still not complete. Especially the stats module is not explained.
0.89.1 (2012-9-11)
- Re-introduced sympycore as default CAS. It is MUCH faster than sympy. Now comes packaged with PyMacLab.
- Also decided to always package the latest (working and tested) parallel python(pp) library with PyMacLab.
- PyMacLab’s parser now also replaces substituted items in the closed form steady state section.
- A new parameter can be passed to pymaclab.newMOD(mesg=True|False) to generate diagnosis print-outs during instantiation.
- Another new parameter is pymaclab.newMOD(ncpus=’auto’|INT) where INT is some integer. Number of CPU cores to be used. Default=1.
- Another new parameter is pymaclab.newMOD(mk_hessian=True|False). Should expensive Hessian be computed? Default=True.
- PyMacLab now supports 5 different ways of finding a DSGE model’s steady state.
- One of the 5 SS methods uses externally passed arguments pymaclab.newMOD(use_focs=[],ssidic={}) to use FOCS to solve for SS.
- One-off and queued dynamic run-time DSGE model updaters objects have been added
- Improved various DSGE model templates. Monika Merz’s unemployment RBC DSGE model is now working.
- Further improvements and additions to the online documentation
0.88.1 (2012-9-3)
- PyMacLab now only depends on Sympy and no longer the outdated Sympycore.
- Significantly improved documentation, now on its way of being first draft.
- Translated some model files to make use of new functions.
- Deprecated alternative ways of specifying law of motion of exogenous states.
- Added new SS{EXPRESSION} steady-state conversion feature to Variable Substitution section.
- DIFF{EXPRESSION} now also works for steady state expressions w.r.t. steady state variables.
0.85 (2012-08-30)
- Added Sphinx Documentation with API Section.
- Analytical differentiation using DIFF{EXPRESSION,x(t)} now possible in Substitution Section of modfiles.
- Forward and Backward operators FF_X{EXPRESSION} and BB_X{EXPRESSION} for X=1...N now possible in Substitution section of modfiles.
0.8 (2012-08-21)
First public release.
