gretl 2021b released
by Allin Cottrell
See http://gretl.sourceforge.net/
Mac users note: we now have a specific macOS package for arm64, aka
"Apple silicon" or "M1".
Here's the change log:
2021-05-04 version 2021b
- New function trigamma(): second derivative of lngamma
- New function midasmult(): gives MIDAS multipliers
- New command "bds": BDS nonlinearity test
- gdtb data format: make the new variant the default
- tighten up on defbundle() syntax: no empty arguments
allowed
- array definition: enforce the specific choice of type
- "wls" command, with 0/1 weights: compute $yhat and $uhat
for the excluded observations
- "dpanel" estimation via the GUI: make the --dpdstyle flag
configurable
- "dpanel" --verbose switch: provide some information on the
instruments used
- "adf" command: support more accurate inference with
improved p-values or critical values, for the GLS case
in particular
- "xtab" command: clarify that the $result (matrix) accessor
is just for the bivariate case
- "clear" command: add --functions option to remove all hansl
functions from memory
- "restrict" command: add "inject" keyword to support use of
an array of strings to specify restrictions
- "param_names" keyword for nls, mle, gmm: accept an array of
strings as argument
- binary probit and logit: offer Estrella's pseudo R-squared
as an alternative to McFadden, via --estrella option
- The functions mean, sum, sd, var, wmean, wsd and wvar now
accept an optional boolean argument; specific to the
cross-sectional statistics produced when list arguments
are given, this allows skipping of missing values.
- hdprod(): introduce "shorthand" syntax (one argument only)
- dbnomics addon: speed up retrieval of data
- user-defined functions: allow overloading of numeric
arguments and return value (scalar, series or matrix)
- user-defined function parameters: enforce the "const" flag
more consistently
- gretl timer ("stopwatch"): provide a separate timer for each
level of function execution
- GUI usage of geoplot addon: make it easier to save an edited
map as GeoJSON
- GUI model specification dialog: enable interactive search in
lists of series
- GUI, saving contents of bundles: enable saving of integer
members
- GUI, handle dependencies when installing function packages
- GUI script editor: improve implementation of "smart tab"
- Fix bug: breakage in computing out-of-sample forecasts from
VECMs
- Fix bug: possible crash when displaying a matrix with very
long column names in the GUI program
- Fix bug: broken covariance matrix from mols() with a large
number of regressors
- Fix bug: crash on applying postfix "++" to a submatrix
- macOS: first release for arm64
