http://gretl.sourceforge.net/ 6/13/2008 version 1.7.5 - max() and min() functions: extend the syntax to allow a list argument - Reading CSV data: automatically substitute '_' for illegal characters in variable names - Support DESTDIR for make install - Add Weibull distribution to the various gretl probability distribution functions - Fix for parsing a restriction with leading numerical term - New functions: pdf, sdc, msortby - User-defined functions: allow a descriptive string to accompany each parameter, for use in GUI - Add $unit accessor to get a panel unit index - Add "--breusch-pagan" option to lmtest command (with --robust option to use the Koenker robust variance estimator); also add this test to the GUI - Fix some bugs in sub-sampling of panel datasets - Revise the GUI for setting the sample range for panel data - Improvements for panel time-series graphs - Fix bug in importing data with long numeric observation labels - printf command: allow matrices in place of scalars (e.g. using "%f" or "%g" conversion) - GUI script output window: add option of making output "sticky" (running a script appends to text) - Add log-axis option to GUI graph editing dialog - GUI program: add right-click popup menus to more windows - Fix bugs 1929957, 1922915, 1951681, 1954428, 1954838, 1960861, 1969680, 1972629, 1972613, 1980775 - Add guard against unmatched "if" in loops, functions and scripts - Fix bug: VARs and equation systems not getting removed as "last model" on exit from user-defined functions, which could cause strange errors in complex scripts - Fix for forecasts from equation systems displayed in the GUI program - Updates to some screenshots in the User's Guide - pca command: add --covariance option to base the analysis on the covariance matrix instead of the correlation matrix - corr command: document the --uniform option and add it to the GUI - Fix bug: loops inside conditionals inside a loop were not executing properly in some cases - X-Y scatterplot: add option of controlling for a third variable - hsk command: fix for the case where the model includes a dummy that is specific to a particular observation - arima specification dialog: add checkbox for basing standard errors on the Hessian - store, outfile, etc.: if the filename starts with "~/", expand this to the user's home directory, if possible - Search for data file collections: add the user's gretl data directory ("dotdir") to the path searched - "append" command: try harder to make this do what the user is most likely to want in the case of panel data - frequency distribution in GUI: allow choice of bin size, as with frequency plot - fixed effects estimation: print the average constant - eigengen function: make this behave as the manual says - OLS anova: add p-value for the F-statistic - Fix VECM forecast graph in GUI ("pre-forecast" fitted values were not integrated) - "open" command: add options for controlling importation from spreadsheets - add "set debug" option for deugging user-defined functions - GUI function package: add option to save the packaged functions as a regular gretl script - Fix bug in modification of LMF autocorrelation test (bug was introduced in gretl 1.7.4) - Script editor: add option to show line numbers - Native database windows: add right-click popup menu - Local function package listing: sort alphabetically - logit/probit: add code to detect perfect classifiers - "tabprint" model-printing command: add --rtf option to produce RTF output rather than LaTeX - Windows build: update to Lapack version 3.1.1 - Add quantile regression ("quantreg" command) - Add experimental support for importing data from an external database via ODBC - Add "normest" command to test a series for normality, with options of Doornik-Hansen, Shapiro-Wilk or Jarque-Bera - Model window, confidence intervals for coefficients: add option of changing the confidence level from the default of 95 percent; and similarly for confidence ellipses - Add facility for writing and executing R scripts via the gretl GUI - Durbin-Watson statistic: supply a larger table of critical values (thanks to Marcin Blazejowski and Tadeusz Kufel) -- Allin Cottrell Department of Economics Wake Forest University, NC
