3 * linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**.
5 2006-04-28 Jason Stover <jhs@math.gcsu.edu>
7 * linreg.c (pspp_linreg_get_vars): New function. Fills an array with
8 pointers to the variables used in the model.
10 * linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
11 to access variables in a model.
13 * coefficient.c (pspp_linreg_coeff_init): Set the variable
14 associated with the intercept term to NULL.
16 2006-04-26 Jason Stover <jhs@math.gcsu.edu>
18 * linreg.h: Added a pointer to predicted values.
20 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
23 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
25 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
28 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
30 * linreg.h: Added a pointer to a variable to store the resduals.
32 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
33 variable pointer to NULL.
35 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
37 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
38 void to match definition of trns_proc_func.
40 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
42 * linreg.c (pspp_linreg_cache_free): Return a bool.
44 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
46 * predict.c (pspp_linreg_predict): Change prototype to match
47 struct pspp_linreg_cache_struct's predict member.
48 * predict.c (pspp_linreg_residual): Change prototype to match
49 struct pspp_linreg_cache_struct's residual member.
51 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
53 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
54 0, instead of NULL, because it's an integer type.
56 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
58 * linreg.c (pspp_linreg): Move declaration before code for C90
61 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
63 * predict.c (pspp_linreg_predict): Do something sensible even with
66 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
68 * predict.c (pspp_linreg_predict): Improved handling of null
71 * predict.c (pspp_linreg_residuals): New function.
73 * coefficient.c: Improved handling of null pointer args.
75 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
77 * predict.c: New file. pspp_linreg_predict() uses a linear model
78 to return a predicted value of the dependent variable.
80 * coefficient.c: Added pspp_linreg_coeff_get_est() and
81 pspp_linreg_coeff_get_std_err() to access estimated values of
82 coefficients and standard errors.
84 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
86 * coefficient.c: Added pspp_linreg_get_coeff() to find a
87 coefficient corresponding to a variable/value combination.
89 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
91 * Moved files from src directory
