See http://gretl.sourceforge.net/ 2019-05-21 version 2019b - New command "panplot": plot a single panel-data series - "print" command: new --range option to control the range to print for series, matrices, arrays and strings - New command "bkw", now separated from the "vif" command - "smpl" command: add --unit option for panel data - "intreg" and "tobit" commands: add --opg option - "fcast" command: add some support for panel data - "add" command: ensure that the robust option for the target model is respected in the panel-data case - "logistic" command: enable --robust, --cluster and --fixed-effects options - "plot" (block) command: make the "data" argument optional, allowing creation of formula-based plots - New accessor $now to get current time/date, plus new functions strftime() and strptime() - New accessor $parnames to get array of parameter names from a model - New function feval(): evaluate a function by name - New function Lsolve(), using precomputed Cholesky factor - New function isoweek() to get ISO 8601 week number - seasonals() function: use ISO 8601 week numbers for dated weekly data - epochday() function: support YYYYMMDD input - randgen() function: support the logistic distribution - firstobs() and lastobs() functions: add optional boolean argument to restrict the check to the current sample - argname() function: add optional fallback argument - Speed up rank() function for far-from-square matrices - Stata dta importer: fix for opening of very large files - Stata dta exporter: fix breakage on MS Windows - LaTeX output fix: be sure to TeX-escape series names when printing var F-tests output - Obscure fix: enable deletion of "time" from a list supplied as a function argument - GUI convenience: remember dbnomics search string - GUI: disallow execution of a script when one is already in progress (to prevent crashing) - GUI: enable saving of model as bundle under model-window Save menu - GUI, "View as equation" option for models: enable for cases with more than 5 regressors - GUI fix: some of the example scripts referenced in the GUI command help were not being found - Add configure option --disable-gmp: not recommended for general use, but can be helpful in some build contexts where libgmp is not readily available - Allow use of "dataset sortby" in loops - Document the --all-cols option for the "open" command - User's Guide: beef up the Numerical Methods chapter - Allow use of undefined symbols in the right-hand operand of "&&": don't flag an error unless the left-hand operand evaluates as true -- Allin Cottrell Department of Economics Wake Forest University, NC
