3 * linreg.h: Added a pointer to predicted values.
5 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
8 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
10 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
13 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
15 * linreg.h: Added a pointer to a variable to store the resduals.
17 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
18 variable pointer to NULL.
20 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
22 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
23 void to match definition of trns_proc_func.
25 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
27 * linreg.c (pspp_linreg_cache_free): Return a bool.
29 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
31 * predict.c (pspp_linreg_predict): Change prototype to match
32 struct pspp_linreg_cache_struct's predict member.
33 * predict.c (pspp_linreg_residual): Change prototype to match
34 struct pspp_linreg_cache_struct's residual member.
36 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
38 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
39 0, instead of NULL, because it's an integer type.
41 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
43 * linreg.c (pspp_linreg): Move declaration before code for C90
46 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
48 * predict.c (pspp_linreg_predict): Do something sensible even with
51 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
53 * predict.c (pspp_linreg_predict): Improved handling of null
56 * predict.c (pspp_linreg_residuals): New function.
58 * coefficient.c: Improved handling of null pointer args.
60 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
62 * predict.c: New file. pspp_linreg_predict() uses a linear model
63 to return a predicted value of the dependent variable.
65 * coefficient.c: Added pspp_linreg_coeff_get_est() and
66 pspp_linreg_coeff_get_std_err() to access estimated values of
67 coefficients and standard errors.
69 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
71 * coefficient.c: Added pspp_linreg_get_coeff() to find a
72 coefficient corresponding to a variable/value combination.

76 * Moved files from src directory
