| 1.9.8cvs | Apr 2, 2012 | New Release | · GUI: support use of named lists in the model specification dialog and other contexts · GUI: add option of making the script editor and the model viewer windows use tabs · GUI: add "reformat" option to summary statistics window for single series GUI: add keyboard shortcut help file · Add a new practice script illustrating advanced use of mle command, and extend the discussion of mle in the User's Guide · New function pxsum(): computes the cross-sectional sum of a series in the context of panel data - stack() function for panel data: allow '*' in forming list of series · Compaction of daily to weekly data: enable this even if the daily data are not dated · "panel" command: add --nerlove option to use Nerlove's transformation in the context of the random effects estimator · "system" command: various small fixes and enhancements, including greater computational efficiency |
| 1.9.7cvs | Dec 27, 2011 | New Release | · Add two nonparametric estimators: William Cleveland's loess and the Nadaraya-Watson estimator; these are available via the new functions loess() and nadarwat(), and they're also in the GUI Model menu · Binary logit and probit: re-implement using Newton-Raphson for greater numerical stability · Documentation updates, including a new chapter on Nonparametric methods in the User's Guide · "store" command: add a --decimal-comma option to export "CSV" data using "," as decimal character (and ";" as column delimiter) · "leverage" command: add a --quiet option and add calculation of the cross-validation criterion (available via the $test accessor) · "rmplot" command (range-mean plot): add a --trim option to discard the minimum and maximum from each sub-sample · "gnuplot" command: enhance the --with-lines option to permit using lines for some series and points for others · "scatters" command: add a --matrix option and increase the maximum number of plots to 16 |
