+
+       * regression.q (run_regression): Tell the user when the data
+       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.
+
+2007-03-29  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (prepare_data): New function.
+
+       * regression.q (compute_moments): New function.
+
+2007-03-18  Ben Pfaff  <blp@gnu.org>
+
+       * crosstabs.q (static var write): Rename write_style to avoid
+       conflict with POSIX function of same name.
+
+2007-03-16  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (run_regression): Added support for moments.

+Sat Feb 17 08:16:00 2007  Ben Pfaff  <blp@gnu.org>
+
+       * flip.c (flip_sink_create): Improve error message when temporary
+       file cannot be created.
+
+Tue Feb  6 19:58:03 2007  Ben Pfaff  <blp@gnu.org>
+
+       * flip.c (flip_file): Give better error message on end-of-file.
+
+2007-02-04  Jason Stover  <jhs@math.gcsu.edu>
+
+       * 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.
+       
+       * aggregate.c (parse_aggregate_functions) Initialize
+       function_name.

        Simplify missing value handling.
