5 * moments.c (calc_moments): Use gsl_finite instead of finite, as a
6 stopgap measure for portability until appropriate gnulib modules
9 2008-03-10 Jason Stover <jhs@debs.hoobahooba.net>
11 * coefficient.c (pspp_linreg_get_coeff): Removed use of
12 coefficient 0 as intercept.
14 2008-03-01 Jason Stover <jhs@math.gcsu.edu>
16 * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
19 * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
20 a result beyond the last coefficient, or start with a coefficient
21 beyond the last one if there is only one.
23 2007-06-06 Ben Pfaff <blp@gnu.org>
25 Adapt case sources, sinks, and clients of procedure code to the
28 * automake.mk: Add new files.
30 * levene.c: Adapt to new casereaders. Abstract better.
36 * sort.c: Rewrite in terms of case_ordering, merger.
38 2007-05-31 Jason Stover <jhs@math.gcsu.edu>
40 * interaction.c: New file.
41 * interaction.h : New file.
43 Mon Feb 5 15:42:14 2007 Ben Pfaff <blp@gnu.org>
45 * moments.c (moments_pass_two): Reduce number of multiplications.
47 Thu Dec 7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
49 * factor-stats.c factor-stats.h: Changed independent values to
50 be pointers rather than copies.
52 Wed Dec 6 21:14:59 2006 Ben Pfaff <blp@gnu.org>
54 * coefficient.c: (pspp_coeff_get_value) Compare variable pointers
55 instead of variable indexes.
56 (pspp_linreg_get_coeff) Ditto.
57 (design_matrix_col_to_var_index) Removed.
58 (design_matrix_col_to_var) Compare variable pointers
59 instead of variable indexes.
60 (cmp_dm_var_index) Ditto.
61 (design_matrix_var_to_column) Ditto.
62 (dm_var_to_last_column) Ditto.
64 Sun Nov 5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
66 * levene.c levene.h Changed to use the new casefilter structure.
68 2006-07-15 Jason Stover <jhs@math.gcsu.edu>
70 * coefficient.c (pspp_coeff_init): Make design_matrix arg const.
72 2006-07-14 Jason Stover <jhs@math.gcsu.edu>
74 * coefficient.c (pspp_coeff_init): Removed use of
75 pspp_linreg_cache to make the routines more generally useful.
77 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
79 * coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
81 * coefficient.c: Moved to src/math.
83 * coefficient.h: Moved to src/math.
85 Tue May 9 21:09:37 2006 Ben Pfaff <blp@gnu.org>
87 * sort.c (sort_active_file_to_casefile): Check return value of
88 multipass_procedure().
90 Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
92 Continue reforming procedure execution. In this phase, get rid of
93 many global variables, consolidating procedure execution in
94 procedure.c. Encapsulate transformations in new "struct
95 trns_chain". Also, change implementation of N OF CASES, FILTER,
96 and PROCESS IF from special cases to transformations.
98 * sort.c: (prepare_to_sort_active_file) Don't run a procedure
100 (sort_active_file_in_place) Rewrite to run a procedure, capture
101 the output, sort the output, and set that as the source for the
103 (struct sort_to_casefile_cb_data) New structure.
104 (sort_to_casefile_callback) New function.
105 (sort_active_file_to_casefile) Rewrite to use
106 multipass_procedure().
