+
+       * linreg.c (pspp_linreg): For the QR method of getting the least
+       squares estimates, store intercept in cache->intercept
+       instead of coefficienc structure. Partial fix of bug 22788.
+
+2008-03-10  Jason Stover  <jhs@math.gcsu.edu>
+
+       * linreg.c (pspp_linreg): Remove use of coefficient 0 as intercept.
+
+2008-03-08  Jason Stover  <jhs@wonko.gcsu.edu>
+
+       * linreg.c (pspp_linreg_get_vars): Clean up the loop that searches
+       for coefficient/variable matches. Fix for bug 22419.
+
+2008-02-28  Jason Stover  <jhs@math.gcsu.edu>
+
+       * linreg.c (has_coefficient): New function.
+
+       * linreg.c (pspp_linreg_predict): Fix bug 22419.

+
+       * 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.

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