+
+	* covariance-matrix.c (covariance_pass_one): New file, new function.
+
+2008-06-21  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.c (pspp_linreg): Accept a struct design_matrix.  Use new
+	accessor functions pspp_coeff_get_mean, pspp_coeff_get_sd.  New
+	functions pspp_linreg_get_indep_variable_mean,
+	pspp_linreg_set_indep_variable_mean,
+	pspp_linreg_get_indep_variable_sd,
+	pspp_linreg_set_indep_variable_sd. Altered pspp_linreg_get_coeff
+	to use accessor function pspp_coeff_var_to_coeff.
+
+	* coefficient.c: New functions pspp_coeff_get_mean,
+	pspp_coeff_set_mean, pspp_coeff_get_sd, pspp_coeff_set_sd,
+	pspp_coeff_var_to_coeff. Added doubles to hold mean and standard
+	deviation in struct varinfo.
+
+2008-06-14  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg/: moved linreg.[ch] to src/math.
+
+2008-05-15  Ben Pfaff  <blp@gnu.org>
+
+	Patch #6512.
+
+	* moments.c (calc_moments): Use gsl_finite instead of finite, as a
+	stopgap measure for portability until appropriate gnulib modules
+	are available.
+
+2008-03-10  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.c (pspp_linreg_get_coeff): Removed use of
+	coefficient 0 as intercept.
+
+2008-03-01  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.c (pspp_coeff_init): Ensure first arg is not a null
+	pointer.
+
+	* coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
+	a result beyond the last coefficient, or start with a coefficient
+	beyond the last one if there is only one.
+
+2007-06-06  Ben Pfaff  <blp@gnu.org>
+
+	Adapt case sources, sinks, and clients of procedure code to the
+	new infrastructure.
+
+	* automake.mk: Add new files.
+	
+	* levene.c: Adapt to new casereaders.  Abstract better.
+
+	* merge.c: New file.
+
+	* merge.h: New file.
+
+	* sort.c: Rewrite in terms of case_ordering, merger.

+	* interaction.c: New file.
+	* interaction.h : New file.
+

+	* moments.c (moments_pass_two): Reduce number of multiplications.
+
+Thu Dec  7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
+
+	* factor-stats.c factor-stats.h: Changed independent values to 
+	be pointers rather than copies.
+
+Wed Dec  6 21:14:59 2006  Ben Pfaff  <blp@gnu.org>
+
+	* coefficient.c: (pspp_coeff_get_value) Compare variable pointers
+	instead of variable indexes.
+	(pspp_linreg_get_coeff) Ditto.
+	(design_matrix_col_to_var_index) Removed.
+	(design_matrix_col_to_var) Compare variable pointers
+	instead of variable indexes.
+	(cmp_dm_var_index) Ditto.
+	(design_matrix_var_to_column) Ditto.
+	(dm_var_to_last_column) Ditto.
+
+Sun Nov  5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
+
+	* levene.c levene.h Changed to use the new casefilter structure.
+
+2006-07-15  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.c (pspp_coeff_init): Make design_matrix arg const.
+
+2006-07-14  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.c (pspp_coeff_init): Removed use of
+	pspp_linreg_cache to make the routines more generally useful.
+
+2006-05-19  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
+
+	* coefficient.c: Moved to src/math.
+
+	* coefficient.h: Moved to src/math.
+
+Tue May  9 21:09:37 2006  Ben Pfaff  <blp@gnu.org>
+
+	* sort.c (sort_active_file_to_casefile): Check return value of
+	multipass_procedure().
+
+Wed May  3 23:06:43 2006  Ben Pfaff  <blp@gnu.org>
+
+	Continue reforming procedure execution.  In this phase, get rid of
+	many global variables, consolidating procedure execution in
+	procedure.c.  Encapsulate transformations in new "struct
+	trns_chain".  Also, change implementation of N OF CASES, FILTER,
+	and PROCESS IF from special cases to transformations.
+	 
+	* sort.c: (prepare_to_sort_active_file) Don't run a procedure
+	here.
+	(sort_active_file_in_place) Rewrite to run a procedure, capture
+	the output, sort the output, and set that as the source for the
+	next procedure.
+	(struct sort_to_casefile_cb_data) New structure.
+	(sort_to_casefile_callback) New function.
+	(sort_active_file_to_casefile) Rewrite to use
+	multipass_procedure().
