+
+	* linreg.c (has_coefficient): New function.

+
+	* linreg.c (pspp_linreg_cache_free): Partial fix of memory leak,
+	bug 21056.

+
+	* 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.

+	freeing.

+
+	* linreg.c: (pspp_linreg_get_vars) Compare variable pointers
+	instead of variable indexes.

+
+	* linreg.h: Made linreg_cache's coeff a pspp_linreg_coeff**.

+
+	* 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.
