I’m excited to announce a new release of the gretl4py Python module! Version 0.50 includes significant updates, upgrades, and bug fixes. The highlights are:

• Several bugs fixed (including the one related to exporting nested bundles to a dictionary)

• Extensive documentation updates

• General libgretl printer now available as gretl.print()

• Code refactoring for improved clarity and simplicity

• Official interface to libgretl’s genr added (gretl.genr())

• Robustified install.py (thanks, Allin!)

• New test: fractint

• New _gretl.Dataset methods: ::hurst(), ::xcorrgm(), ::pca(), ::rename()

• New free functions: corr(), cov(), pkg()

• New GretlPackage methods: ::get_functions(), ::get_help()

• GretlBundle::pop() method added + enhanced [] operator

• New GretlBundle constructor for on-the-fly bundle creation (similar to gretl’s _() function)

• get_data() now supports a quiet option

• Marked nls, mle, gmm, and system estimators as experimental

• Refactored GretlModel::fcast() to mimic libgretl’s fcast command

• New GretlModel::dataset attribute points directly to the dataset used for model estimation

• _gretl.Dataset::varnames() method added as ::varnames attribute

• New _gretl.Dataset::summary() method

• GretlPackage examples added for BACE, BayTool, BMA, BVAR, criteria, gig, ParMA, SVAR, and TVC

• GretlPackage parameters now accept both positional (*args) and keyword (**kwargs) arguments

Have fun exploring the new features!

Best regards,
