+
+	* 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.

+	associated with the intercept term to NULL.

+	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
