3 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
6 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
8 * linreg.h: Added a pointer to a variable to store the resduals.
10 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
11 variable pointer to NULL.
13 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
15 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
16 void to match definition of trns_proc_func.
18 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
20 * linreg.c (pspp_linreg_cache_free): Return a bool.
22 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
24 * predict.c (pspp_linreg_predict): Change prototype to match
25 struct pspp_linreg_cache_struct's predict member.
26 * predict.c (pspp_linreg_residual): Change prototype to match
27 struct pspp_linreg_cache_struct's residual member.
29 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
31 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
32 0, instead of NULL, because it's an integer type.
34 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
36 * linreg.c (pspp_linreg): Move declaration before code for C90
39 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
41 * predict.c (pspp_linreg_predict): Do something sensible even with
44 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
46 * predict.c (pspp_linreg_predict): Improved handling of null
49 * predict.c (pspp_linreg_residuals): New function.
51 * coefficient.c: Improved handling of null pointer args.
53 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
55 * predict.c: New file. pspp_linreg_predict() uses a linear model
56 to return a predicted value of the dependent variable.
58 * coefficient.c: Added pspp_linreg_coeff_get_est() and
59 pspp_linreg_coeff_get_std_err() to access estimated values of
60 coefficients and standard errors.
62 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
64 * coefficient.c: Added pspp_linreg_get_coeff() to find a
65 coefficient corresponding to a variable/value combination.

69 * Moved files from src directory
