3 * linreg.h: Added a pointer to a variable to store the resduals.
5 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
6 variable pointer to NULL.
8 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
10 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
11 void to match definition of trns_proc_func.
13 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
15 * linreg.c (pspp_linreg_cache_free): Return a bool.
17 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
19 * predict.c (pspp_linreg_predict): Change prototype to match
20 struct pspp_linreg_cache_struct's predict member.
21 * predict.c (pspp_linreg_residual): Change prototype to match
22 struct pspp_linreg_cache_struct's residual member.
24 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
26 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
27 0, instead of NULL, because it's an integer type.
29 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
31 * linreg.c (pspp_linreg): Move declaration before code for C90
34 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
36 * predict.c (pspp_linreg_predict): Do something sensible even with
39 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
41 * predict.c (pspp_linreg_predict): Improved handling of null
44 * predict.c (pspp_linreg_residuals): New function.
46 * coefficient.c: Improved handling of null pointer args.
48 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
50 * predict.c: New file. pspp_linreg_predict() uses a linear model
51 to return a predicted value of the dependent variable.
53 * coefficient.c: Added pspp_linreg_coeff_get_est() and
54 pspp_linreg_coeff_get_std_err() to access estimated values of
55 coefficients and standard errors.
57 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
59 * coefficient.c: Added pspp_linreg_get_coeff() to find a
60 coefficient corresponding to a variable/value combination.

64 * Moved files from src directory
