3 * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
6 * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
7 a result beyond the last coefficient, or start with a coefficient
8 beyond the last one if there is only one.
10 2007-06-06 Ben Pfaff <blp@gnu.org>
12 Adapt case sources, sinks, and clients of procedure code to the
15 * automake.mk: Add new files.
17 * levene.c: Adapt to new casereaders. Abstract better.
23 * sort.c: Rewrite in terms of case_ordering, merger.
25 2007-05-31 Jason Stover <jhs@math.gcsu.edu>
27 * interaction.c: New file.
28 * interaction.h : New file.
30 Mon Feb 5 15:42:14 2007 Ben Pfaff <blp@gnu.org>
32 * moments.c (moments_pass_two): Reduce number of multiplications.
34 Thu Dec 7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
36 * factor-stats.c factor-stats.h: Changed independent values to
37 be pointers rather than copies.
39 Wed Dec 6 21:14:59 2006 Ben Pfaff <blp@gnu.org>
41 * coefficient.c: (pspp_coeff_get_value) Compare variable pointers
42 instead of variable indexes.
43 (pspp_linreg_get_coeff) Ditto.
44 (design_matrix_col_to_var_index) Removed.
45 (design_matrix_col_to_var) Compare variable pointers
46 instead of variable indexes.
47 (cmp_dm_var_index) Ditto.
48 (design_matrix_var_to_column) Ditto.
49 (dm_var_to_last_column) Ditto.
51 Sun Nov 5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
53 * levene.c levene.h Changed to use the new casefilter structure.
55 2006-07-15 Jason Stover <jhs@math.gcsu.edu>
57 * coefficient.c (pspp_coeff_init): Make design_matrix arg const.
59 2006-07-14 Jason Stover <jhs@math.gcsu.edu>
61 * coefficient.c (pspp_coeff_init): Removed use of
62 pspp_linreg_cache to make the routines more generally useful.
64 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
66 * coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
68 * coefficient.c: Moved to src/math.
70 * coefficient.h: Moved to src/math.
72 Tue May 9 21:09:37 2006 Ben Pfaff <blp@gnu.org>
74 * sort.c (sort_active_file_to_casefile): Check return value of
75 multipass_procedure().
77 Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
79 Continue reforming procedure execution. In this phase, get rid of
80 many global variables, consolidating procedure execution in
81 procedure.c. Encapsulate transformations in new "struct
82 trns_chain". Also, change implementation of N OF CASES, FILTER,
83 and PROCESS IF from special cases to transformations.
85 * sort.c: (prepare_to_sort_active_file) Don't run a procedure
87 (sort_active_file_in_place) Rewrite to run a procedure, capture
88 the output, sort the output, and set that as the source for the
90 (struct sort_to_casefile_cb_data) New structure.
91 (sort_to_casefile_callback) New function.
92 (sort_active_file_to_casefile) Rewrite to use
93 multipass_procedure().
95 Sat Apr 29 11:09:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
97 * removed unused variable.
99 Sat Apr 15 18:01:22 2006 Ben Pfaff <blp@gnu.org>
101 * factor-stats.c (metrics_postcalc): Add casts to fix warnings.
103 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
105 * Moved files from src directory
