3 * linreg.c: (pspp_linreg_cache_free) Check for null pointer before
6 Wed Dec 6 21:16:22 2006 Ben Pfaff <blp@gnu.org>
8 * linreg.c: (pspp_linreg_get_vars) Compare variable pointers
9 instead of variable indexes.
11 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
13 * coefficient.c: Moved to src/math.
15 * coefficient.h: Moved to src/math.
17 2006-05-11 Jason Stover <jhs@math.gcsu.edu>
19 * linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**.
21 2006-04-28 Jason Stover <jhs@math.gcsu.edu>
23 * linreg.c (pspp_linreg_get_vars): New function. Fills an array with
24 pointers to the variables used in the model.
26 * linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
27 to access variables in a model.
29 * coefficient.c (pspp_linreg_coeff_init): Set the variable
30 associated with the intercept term to NULL.
32 2006-04-26 Jason Stover <jhs@math.gcsu.edu>
34 * linreg.h: Added a pointer to predicted values.
36 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
39 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
41 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
44 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
46 * linreg.h: Added a pointer to a variable to store the resduals.
48 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
49 variable pointer to NULL.
51 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
53 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
54 void to match definition of trns_proc_func.
56 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
58 * linreg.c (pspp_linreg_cache_free): Return a bool.
60 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
62 * predict.c (pspp_linreg_predict): Change prototype to match
63 struct pspp_linreg_cache_struct's predict member.
64 * predict.c (pspp_linreg_residual): Change prototype to match
65 struct pspp_linreg_cache_struct's residual member.
67 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
69 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
70 0, instead of NULL, because it's an integer type.
72 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
74 * linreg.c (pspp_linreg): Move declaration before code for C90
77 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
79 * predict.c (pspp_linreg_predict): Do something sensible even with
82 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
84 * predict.c (pspp_linreg_predict): Improved handling of null
87 * predict.c (pspp_linreg_residuals): New function.
89 * coefficient.c: Improved handling of null pointer args.
91 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
93 * predict.c: New file. pspp_linreg_predict() uses a linear model
94 to return a predicted value of the dependent variable.
96 * coefficient.c: Added pspp_linreg_coeff_get_est() and
97 pspp_linreg_coeff_get_std_err() to access estimated values of
98 coefficients and standard errors.
100 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
102 * coefficient.c: Added pspp_linreg_get_coeff() to find a
103 coefficient corresponding to a variable/value combination.
105 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
107 * Moved files from src directory
