+
+ * flip.c: Rewrite to be a casereader.
+

+ contain no valid cases.
+
+2007-05-08 Jason Stover <jhs@math.gcsu.edu>
+
+ * regression.q: Partial fix of bug which caused a crash if
+ dependent variable and independent variable were the same.
+
+2007-04-16 John Darrington <john@darrington.wattle.id.au>
+
+ * t-test.q: Changed the output width of reported counts and
+ degrees of freedom, to avoid truncating these values. Thanks
+ to Seth Woolley for reporting this problem. A proper fix involves
+ re-thinking the output driver.
+
+2007-04-12 Jason Stover <jhs@math.gcsu.edu>
+
+ * regression.q (run_regression): Added if (n_data >0) to fix bug
+ 19581.

+
+ * regression.q: Fixed p-value computation in the test for
+ individual regression coefficients.
+
+Mon Jan 15 11:03:20 2007 Ben Pfaff <blp@gnu.org>
+
+ Fix bugs found by valgrind when --enable-debug is used with the
+ new case code. These bugs are hidden when the data set is small
+ enough to find in memory; if a bigger data set that would overflow
+ to disk were used, then data corruption would occur.
+
+ * chisquare.c (create_freq_hash): Pass free_freq_mutable_hash to
+ hsh_create as free function. Make copy of data put into hash.
+
+ * oneway.q (free_value): New function.
+ (run_oneway): Use free_value as arg to hsh_create. Make copy of
+ data put into hash.
+
+ * rank.q (rank_cases): Don't access data in case after we've given
+ away the case.
+
+Tue Jan 9 19:16:11 2007 Ben Pfaff <blp@gnu.org>
+
+ Fix bug #18739.

+ function_name.

+ `enum mv_class exclude'. Remove `int missing', add `bool
+ saw_missing'. Update users.
+
+ * descriptives.c (struct dsc_trns): Removed `int
+ include_user_missing', add `enum mv_class exclude'. Update users.
+ (struct dsc_proc): Ditto.

+ when /FORMAT=nolabels was given.

+
+ Make it possible to pull cases from the active file with a
+ function call, instead of requiring indirection through a callback
