3 * linreg.c (pspp_linreg_get_vars): New function. Fills an array with
4 pointers to the variables used in the model.
6 * linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
7 to access variables in a model.
9 * coefficient.c (pspp_linreg_coeff_init): Set the variable
10 associated with the intercept term to NULL.
12 2006-04-26 Jason Stover <jhs@math.gcsu.edu>
14 * linreg.h: Added a pointer to predicted values.
16 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
19 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
21 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
24 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
26 * linreg.h: Added a pointer to a variable to store the resduals.
28 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
29 variable pointer to NULL.
31 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
33 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
34 void to match definition of trns_proc_func.
36 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
38 * linreg.c (pspp_linreg_cache_free): Return a bool.
40 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
42 * predict.c (pspp_linreg_predict): Change prototype to match
43 struct pspp_linreg_cache_struct's predict member.
44 * predict.c (pspp_linreg_residual): Change prototype to match
45 struct pspp_linreg_cache_struct's residual member.
47 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
49 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
50 0, instead of NULL, because it's an integer type.
52 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
54 * linreg.c (pspp_linreg): Move declaration before code for C90
57 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
59 * predict.c (pspp_linreg_predict): Do something sensible even with
62 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
64 * predict.c (pspp_linreg_predict): Improved handling of null
67 * predict.c (pspp_linreg_residuals): New function.
69 * coefficient.c: Improved handling of null pointer args.
71 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
73 * predict.c: New file. pspp_linreg_predict() uses a linear model
74 to return a predicted value of the dependent variable.
76 * coefficient.c: Added pspp_linreg_coeff_get_est() and
77 pspp_linreg_coeff_get_std_err() to access estimated values of
78 coefficients and standard errors.
80 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
82 * coefficient.c: Added pspp_linreg_get_coeff() to find a
83 coefficient corresponding to a variable/value combination.
85 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
87 * Moved files from src directory
