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)
