	* linreg.h: Added a pointer to a variable to store the resduals.

	* linreg.c (pspp_linreg_cache_alloc): Initialize the residual
	variable pointer to NULL.

2006-04-17  Jason Stover  <jason@wonko.gcsu.edu>

	* linreg.c (pspp_linreg_cache_free): Accept a pointer of type
	void to match definition of trns_proc_func.

2006-04-17  Jason Stover  <jhs@math.gcsu.edu>

	* linreg.c (pspp_linreg_cache_free): Return a bool.

Sat Apr 15 18:03:01 2006  Ben Pfaff  <blp@gnu.org>

	* predict.c (pspp_linreg_predict): Change prototype to match
	struct pspp_linreg_cache_struct's predict member.
	* predict.c (pspp_linreg_residual): Change prototype to match
	struct pspp_linreg_cache_struct's residual member.

Sat Apr 15 18:01:39 2006  Ben Pfaff  <blp@gnu.org>

	* coefficient.c (pspp_linreg_get_coeff): Compare n_indeps against
	0, instead of NULL, because it's an integer type.

Mon Apr  3 13:20:54 2006  Ben Pfaff  <blp@gnu.org>

	* linreg.c (pspp_linreg): Move declaration before code for C90
	compliance.

2006-04-09  Jason Stover  <jhs@math.gcsu.edu>

	* predict.c (pspp_linreg_predict): Do something sensible even with
	bad input.

2006-04-07  Jason Stover  <jhs@math.gcsu.edu>

	* predict.c (pspp_linreg_predict): Improved handling of null
	pointer args.

	* predict.c (pspp_linreg_residuals): New function.

	* coefficient.c: Improved handling of null pointer args.

2006-04-05  Jason Stover  <jhs@math.gcsu.edu>

	* predict.c: New file. pspp_linreg_predict() uses a linear model
	to return a predicted value of the dependent variable.

	* coefficient.c: Added pspp_linreg_coeff_get_est() and
	pspp_linreg_coeff_get_std_err() to access estimated values of
	coefficients and standard errors.

2006-04-03  Jason Stover  <jhs@math.gcsu.edu>

	* coefficient.c: Added pspp_linreg_get_coeff() to find a
	coefficient corresponding to a variable/value combination.
