3 * linreg.c (pspp_linreg): Accept a struct design_matrix. Use new
4 accessor functions pspp_coeff_get_mean, pspp_coeff_get_sd. New
5 functions pspp_linreg_get_indep_variable_mean,
6 pspp_linreg_set_indep_variable_mean,
7 pspp_linreg_get_indep_variable_sd,
8 pspp_linreg_set_indep_variable_sd. Altered pspp_linreg_get_coeff
9 to use accessor function pspp_coeff_var_to_coeff.
11 * coefficient.c: New functions pspp_coeff_get_mean,
12 pspp_coeff_set_mean, pspp_coeff_get_sd, pspp_coeff_set_sd,
13 pspp_coeff_var_to_coeff. Added doubles to hold mean and standard
14 deviation in struct varinfo.
16 2008-06-14 Jason Stover <jhs@math.gcsu.edu>
18 * linreg/: moved linreg.[ch] to src/math.
20 2008-05-15 Ben Pfaff <blp@gnu.org>
24 * moments.c (calc_moments): Use gsl_finite instead of finite, as a
25 stopgap measure for portability until appropriate gnulib modules
28 2008-03-10 Jason Stover <jhs@math.gcsu.edu>
30 * coefficient.c (pspp_linreg_get_coeff): Removed use of
31 coefficient 0 as intercept.
33 2008-03-01 Jason Stover <jhs@math.gcsu.edu>
35 * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
38 * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
39 a result beyond the last coefficient, or start with a coefficient
40 beyond the last one if there is only one.
42 2007-06-06 Ben Pfaff <blp@gnu.org>
44 Adapt case sources, sinks, and clients of procedure code to the
47 * automake.mk: Add new files.
49 * levene.c: Adapt to new casereaders. Abstract better.
55 * sort.c: Rewrite in terms of case_ordering, merger.
57 2007-05-31 Jason Stover <jhs@math.gcsu.edu>
59 * interaction.c: New file.
60 * interaction.h : New file.
62 Mon Feb 5 15:42:14 2007 Ben Pfaff <blp@gnu.org>
64 * moments.c (moments_pass_two): Reduce number of multiplications.
66 Thu Dec 7 15:27:49 WST 2006 John Darrington <john@darrington.wattle.id.au>
68 * factor-stats.c factor-stats.h: Changed independent values to
69 be pointers rather than copies.
71 Wed Dec 6 21:14:59 2006 Ben Pfaff <blp@gnu.org>
73 * coefficient.c: (pspp_coeff_get_value) Compare variable pointers
74 instead of variable indexes.
75 (pspp_linreg_get_coeff) Ditto.
76 (design_matrix_col_to_var_index) Removed.
77 (design_matrix_col_to_var) Compare variable pointers
78 instead of variable indexes.
79 (cmp_dm_var_index) Ditto.
80 (design_matrix_var_to_column) Ditto.
81 (dm_var_to_last_column) Ditto.
83 Sun Nov 5 08:30:32 WST 2006 John Darrington <john@darrington.wattle.id.au>
85 * levene.c levene.h Changed to use the new casefilter structure.
87 2006-07-15 Jason Stover <jhs@math.gcsu.edu>
89 * coefficient.c (pspp_coeff_init): Make design_matrix arg const.
91 2006-07-14 Jason Stover <jhs@math.gcsu.edu>
93 * coefficient.c (pspp_coeff_init): Removed use of
94 pspp_linreg_cache to make the routines more generally useful.
96 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
98 * coefficient.h: Renamed pspp_linreg_coeff to pspp_coeff.
100 * coefficient.c: Moved to src/math.
102 * coefficient.h: Moved to src/math.

107 multipass_procedure().
109 Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
111 Continue reforming procedure execution. In this phase, get rid of
112 many global variables, consolidating procedure execution in
113 procedure.c. Encapsulate transformations in new "struct
114 trns_chain". Also, change implementation of N OF CASES, FILTER,
115 and PROCESS IF from special cases to transformations.
117 * sort.c: (prepare_to_sort_active_file) Don't run a procedure
119 (sort_active_file_in_place) Rewrite to run a procedure, capture
120 the output, sort the output, and set that as the source for the
122 (struct sort_to_casefile_cb_data) New structure.
123 (sort_to_casefile_callback) New function.
124 (sort_active_file_to_casefile) Rewrite to use
125 multipass_procedure().

129 * removed unused variable.
131 Sat Apr 15 18:01:22 2006 Ben Pfaff <blp@gnu.org>
133 * factor-stats.c (metrics_postcalc): Add casts to fix warnings.
135 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
