broken

specifications without an AR component
- "heckit" command: add selection equation regressor list to
$model bundle under the key "zlist"

$test and $pvalue for the Pearson chi-square test in the

- GUI plot editor: support selection of dash patterns for
plots using lines

file type and set the filter accordingly
- Build fix: correct undefined symbol in cephes/iv.c
- Boxplots: fix for incorrect extent of "whiskers" in some
cases
- Boxplots: fix for "collapse" of boxplot when edited in
the GUI, if the locale decimal separator is ','
- GUI fix: the iterate option for groupwise weighted least
squares (Model/Panel menu) had become disconnected
