3 * linreg.c (pspp_linreg_cache_free): Return a bool.
5 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
7 * predict.c (pspp_linreg_predict): Change prototype to match
8 struct pspp_linreg_cache_struct's predict member.
9 * predict.c (pspp_linreg_residual): Change prototype to match
10 struct pspp_linreg_cache_struct's residual member.

14 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
15 0, instead of NULL, because it's an integer type.
17 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
19 * linreg.c (pspp_linreg): Move declaration before code for C90
22 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
24 * predict.c (pspp_linreg_predict): Do something sensible even with
27 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
29 * predict.c (pspp_linreg_predict): Improved handling of null
32 * predict.c (pspp_linreg_residuals): New function.
34 * coefficient.c: Improved handling of null pointer args.
36 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
38 * predict.c: New file. pspp_linreg_predict() uses a linear model
39 to return a predicted value of the dependent variable.
41 * coefficient.c: Added pspp_linreg_coeff_get_est() and
42 pspp_linreg_coeff_get_std_err() to access estimated values of
43 coefficients and standard errors.
45 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
47 * coefficient.c: Added pspp_linreg_get_coeff() to find a
48 coefficient corresponding to a variable/value combination.

52 * Moved files from src directory
