1 2008-03-10 Jason Stover <jhs@debs.hoobahooba.net>
3 * coefficient.c (pspp_linreg_get_coeff): Removed use of
4 coefficient 0 as intercept.
6 2008-03-01 Jason Stover <jhs@math.gcsu.edu>
8 * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
11 * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
12 a result beyond the last coefficient, or start with a coefficient
13 beyond the last one if there is only one.
15 2007-06-06 Ben Pfaff <blp@gnu.org>
17 Adapt case sources, sinks, and clients of procedure code to the
20 * automake.mk: Add new files.
22 * levene.c: Adapt to new casereaders. Abstract better.
28 * sort.c: Rewrite in terms of case_ordering, merger.
30 2007-05-31 Jason Stover <jhs@math.gcsu.edu>
32 * interaction.c: New file.
33 * interaction.h : New file.
35 Mon Feb 5 15:42:14 2007 Ben Pfaff <blp@gnu.org>
37 * moments.c (moments_pass_two): Reduce number of multiplications.
39 Thu Dec 7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
41 * factor-stats.c factor-stats.h: Changed independent values to
42 be pointers rather than copies.
44 Wed Dec 6 21:14:59 2006 Ben Pfaff <blp@gnu.org>
46 * coefficient.c: (pspp_coeff_get_value) Compare variable pointers
47 instead of variable indexes.
48 (pspp_linreg_get_coeff) Ditto.
49 (design_matrix_col_to_var_index) Removed.
50 (design_matrix_col_to_var) Compare variable pointers
51 instead of variable indexes.
52 (cmp_dm_var_index) Ditto.
53 (design_matrix_var_to_column) Ditto.
54 (dm_var_to_last_column) Ditto.
56 Sun Nov 5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
58 * levene.c levene.h Changed to use the new casefilter structure.
60 2006-07-15 Jason Stover <jhs@math.gcsu.edu>
62 * coefficient.c (pspp_coeff_init): Make design_matrix arg const.
64 2006-07-14 Jason Stover <jhs@math.gcsu.edu>
66 * coefficient.c (pspp_coeff_init): Removed use of
67 pspp_linreg_cache to make the routines more generally useful.
69 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
71 * coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
73 * coefficient.c: Moved to src/math.
75 * coefficient.h: Moved to src/math.
77 Tue May 9 21:09:37 2006 Ben Pfaff <blp@gnu.org>
79 * sort.c (sort_active_file_to_casefile): Check return value of
80 multipass_procedure().
82 Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
84 Continue reforming procedure execution. In this phase, get rid of
85 many global variables, consolidating procedure execution in
86 procedure.c. Encapsulate transformations in new "struct
87 trns_chain". Also, change implementation of N OF CASES, FILTER,
88 and PROCESS IF from special cases to transformations.
90 * sort.c: (prepare_to_sort_active_file) Don't run a procedure
92 (sort_active_file_in_place) Rewrite to run a procedure, capture
93 the output, sort the output, and set that as the source for the
95 (struct sort_to_casefile_cb_data) New structure.
96 (sort_to_casefile_callback) New function.
97 (sort_active_file_to_casefile) Rewrite to use
98 multipass_procedure().
100 Sat Apr 29 11:09:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
102 * removed unused variable.
104 Sat Apr 15 18:01:22 2006 Ben Pfaff <blp@gnu.org>
106 * factor-stats.c (metrics_postcalc): Add casts to fix warnings.
108 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
