1 2006-05-19 Jason Stover <jhs@math.gcsu.edu>
3 * coefficient.c: Moved to src/math.
5 * coefficient.h: Moved to src/math.
7 2006-05-11 Jason Stover <jhs@math.gcsu.edu>
9 * linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**.
11 2006-04-28 Jason Stover <jhs@math.gcsu.edu>
13 * linreg.c (pspp_linreg_get_vars): New function. Fills an array with
14 pointers to the variables used in the model.
16 * linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
17 to access variables in a model.
19 * coefficient.c (pspp_linreg_coeff_init): Set the variable
20 associated with the intercept term to NULL.
22 2006-04-26 Jason Stover <jhs@math.gcsu.edu>
24 * linreg.h: Added a pointer to predicted values.
26 * linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
29 2006-04-22 Jason Stover <jhs@debs.hjklfdsss.org>
31 * predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
34 2006-04-18 Jason Stover <jhs@math.gcsu.edu>
36 * linreg.h: Added a pointer to a variable to store the resduals.
38 * linreg.c (pspp_linreg_cache_alloc): Initialize the residual
39 variable pointer to NULL.
41 2006-04-17 Jason Stover <jason@wonko.gcsu.edu>
43 * linreg.c (pspp_linreg_cache_free): Accept a pointer of type
44 void to match definition of trns_proc_func.
46 2006-04-17 Jason Stover <jhs@math.gcsu.edu>
48 * linreg.c (pspp_linreg_cache_free): Return a bool.
50 Sat Apr 15 18:03:01 2006 Ben Pfaff <blp@gnu.org>
52 * predict.c (pspp_linreg_predict): Change prototype to match
53 struct pspp_linreg_cache_struct's predict member.
54 * predict.c (pspp_linreg_residual): Change prototype to match
55 struct pspp_linreg_cache_struct's residual member.
57 Sat Apr 15 18:01:39 2006 Ben Pfaff <blp@gnu.org>
59 * coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
60 0, instead of NULL, because it's an integer type.
62 Mon Apr 3 13:20:54 2006 Ben Pfaff <blp@gnu.org>
64 * linreg.c (pspp_linreg): Move declaration before code for C90
67 2006-04-09 Jason Stover <jhs@math.gcsu.edu>
69 * predict.c (pspp_linreg_predict): Do something sensible even with
72 2006-04-07 Jason Stover <jhs@math.gcsu.edu>
74 * predict.c (pspp_linreg_predict): Improved handling of null
77 * predict.c (pspp_linreg_residuals): New function.
79 * coefficient.c: Improved handling of null pointer args.
81 2006-04-05 Jason Stover <jhs@math.gcsu.edu>
83 * predict.c: New file. pspp_linreg_predict() uses a linear model
84 to return a predicted value of the dependent variable.
86 * coefficient.c: Added pspp_linreg_coeff_get_est() and
87 pspp_linreg_coeff_get_std_err() to access estimated values of
88 coefficients and standard errors.
90 2006-04-03 Jason Stover <jhs@math.gcsu.edu>
92 * coefficient.c: Added pspp_linreg_get_coeff() to find a
93 coefficient corresponding to a variable/value combination.
95 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
97 * Moved files from src directory
