3 * linreg/: moved linreg.[ch] to src/math.
5 2008-05-15 Ben Pfaff <blp@gnu.org>
9 * moments.c (calc_moments): Use gsl_finite instead of finite, as a
10 stopgap measure for portability until appropriate gnulib modules
13 2008-03-10 Jason Stover <jhs@debs.hoobahooba.net>
15 * coefficient.c (pspp_linreg_get_coeff): Removed use of
16 coefficient 0 as intercept.
18 2008-03-01 Jason Stover <jhs@math.gcsu.edu>
20 * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
23 * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
24 a result beyond the last coefficient, or start with a coefficient
25 beyond the last one if there is only one.
27 2007-06-06 Ben Pfaff <blp@gnu.org>
29 Adapt case sources, sinks, and clients of procedure code to the
32 * automake.mk: Add new files.
34 * levene.c: Adapt to new casereaders. Abstract better.
40 * sort.c: Rewrite in terms of case_ordering, merger.
42 2007-05-31 Jason Stover <jhs@math.gcsu.edu>
44 * interaction.c: New file.
45 * interaction.h : New file.
47 Mon Feb 5 15:42:14 2007 Ben Pfaff <blp@gnu.org>
49 * moments.c (moments_pass_two): Reduce number of multiplications.
51 Thu Dec 7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
53 * factor-stats.c factor-stats.h: Changed independent values to
54 be pointers rather than copies.
56 Wed Dec 6 21:14:59 2006 Ben Pfaff <blp@gnu.org>
58 * coefficient.c: (pspp_coeff_get_value) Compare variable pointers
59 instead of variable indexes.
60 (pspp_linreg_get_coeff) Ditto.
61 (design_matrix_col_to_var_index) Removed.
62 (design_matrix_col_to_var) Compare variable pointers
63 instead of variable indexes.
64 (cmp_dm_var_index) Ditto.
65 (design_matrix_var_to_column) Ditto.
66 (dm_var_to_last_column) Ditto.
68 Sun Nov 5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
70 * levene.c levene.h Changed to use the new casefilter structure.
72 2006-07-15 Jason Stover <jhs@math.gcsu.edu>
74 * coefficient.c (pspp_coeff_init): Make design_matrix arg const.
76 2006-07-14 Jason Stover <jhs@math.gcsu.edu>
78 * coefficient.c (pspp_coeff_init): Removed use of
79 pspp_linreg_cache to make the routines more generally useful.
81 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
83 * coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
85 * coefficient.c: Moved to src/math.
87 * coefficient.h: Moved to src/math.
89 Tue May 9 21:09:37 2006 Ben Pfaff <blp@gnu.org>
91 * sort.c (sort_active_file_to_casefile): Check return value of
92 multipass_procedure().
94 Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
96 Continue reforming procedure execution. In this phase, get rid of
97 many global variables, consolidating procedure execution in
98 procedure.c. Encapsulate transformations in new "struct
99 trns_chain". Also, change implementation of N OF CASES, FILTER,
100 and PROCESS IF from special cases to transformations.
102 * sort.c: (prepare_to_sort_active_file) Don't run a procedure
104 (sort_active_file_in_place) Rewrite to run a procedure, capture
105 the output, sort the output, and set that as the source for the
107 (struct sort_to_casefile_cb_data) New structure.
108 (sort_to_casefile_callback) New function.
109 (sort_active_file_to_casefile) Rewrite to use
110 multipass_procedure().
