3 * linreg.c: (pspp_linreg_get_vars) Compare variable pointers
4 instead of variable indexes.
6 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
8 * coefficient.c: Moved to src/math.
10 * coefficient.h: Moved to src/math.
12 2006-05-11 Jason Stover <jhs@math.gcsu.edu>
14 * linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**.
16 2006-04-28 Jason Stover <jhs@math.gcsu.edu>
18 * linreg.c (pspp_linreg_get_vars): New function. Fills an array with
19 pointers to the variables used in the model.
21 * linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
22 to access variables in a model.
24 * coefficient.c (pspp_linreg_coeff_init): Set the variable
25 associated with the intercept term to NULL.
27 2006-04-26 Jason Stover <jhs@math.gcsu.edu>
29 * linreg.h: Added a pointer to predicted values.
31 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
34 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
36 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
39 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
41 * linreg.h: Added a pointer to a variable to store the resduals.
43 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
44 variable pointer to NULL.
46 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
48 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
49 void to match definition of trns_proc_func.
51 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
53 * linreg.c (pspp_linreg_cache_free): Return a bool.
55 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
57 * predict.c (pspp_linreg_predict): Change prototype to match
58 struct pspp_linreg_cache_struct's predict member.
59 * predict.c (pspp_linreg_residual): Change prototype to match
60 struct pspp_linreg_cache_struct's residual member.
62 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
64 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
65 0, instead of NULL, because it's an integer type.
67 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
69 * linreg.c (pspp_linreg): Move declaration before code for C90
72 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
74 * predict.c (pspp_linreg_predict): Do something sensible even with
77 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
79 * predict.c (pspp_linreg_predict): Improved handling of null
82 * predict.c (pspp_linreg_residuals): New function.
84 * coefficient.c: Improved handling of null pointer args.
86 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
88 * predict.c: New file. pspp_linreg_predict() uses a linear model
89 to return a predicted value of the dependent variable.
91 * coefficient.c: Added pspp_linreg_coeff_get_est() and
92 pspp_linreg_coeff_get_std_err() to access estimated values of
93 coefficients and standard errors.
95 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
97 * coefficient.c: Added pspp_linreg_get_coeff() to find a
98 coefficient corresponding to a variable/value combination.
100 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
102 * Moved files from src directory
