+
+	* linreg.c (pspp_linreg_cache_free): Partial fix of memory leak,
+	bug 21056.
+
+2007-08-11  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.h (enum): Dropped ambiguous PSPP_LINREG_SVD in favor of
+	PSPP_LINREG_QR. Added PSPP_LINREG_CONDITIONAL_INVERSE.
+
+	* linreg.c (pspp_linreg): Added scope and comment for use of
+	generalized inverse to solve normal equations.
+
+2007-04-12  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.c: (pspp_linreg_cache_free) Check for null pointer before
+	freeing.
+
+Wed Dec  6 21:16:22 2006  Ben Pfaff  <blp@gnu.org>
+
+	* linreg.c: (pspp_linreg_get_vars) Compare variable pointers
+	instead of variable indexes.
+
+2006-05-19  Jason Stover  <jhs@math.gcsu.edu>
+
+	* coefficient.c: Moved to src/math.
+
+	* coefficient.h: Moved to src/math.
+
+2006-05-11  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**. 
+
+2006-04-28  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.c (pspp_linreg_get_vars): New function. Fills an array with
+	pointers to the variables used in the model.
+
+	* linreg.h: Add a pointer called get_vars to pspp_linreg_get_vars()
+	to access variables in a model.
+
+	* coefficient.c (pspp_linreg_coeff_init): Set the variable
+	associated with the intercept term to NULL.
+
+2006-04-26  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.h: Added a pointer to predicted values.
+
+	* linreg.c (pspp_linreg_cache_alloc): Initialized pointer to
+	predicted values.
+
+2006-04-22  Jason Stover  <jhs@debs.hjklfdsss.org>
+
+	* predict.c (pspp_linreg_residual): Removed unnecessary cast of c_
+	to pspp_linreg_cache.
+
+2006-04-18  Jason Stover  <jhs@math.gcsu.edu>
+
+	* linreg.h: Added a pointer to a variable to store the resduals.

+	variable pointer to NULL.

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

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

+
+	* 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
