+       * linreg.c (pspp_linreg_with_cov): New function to estimate
+       parameters directly from covariance matrix instead of using the
+       entire data set.
+
+       * linreg.c (rearrange_covariance_matrix): New function to ensure
+       the columns of the covariance matrix correspond to the variables
+       in the model.

+       * merge.c merge.h sort.c sort.h: Removed the value_cnt associated
+       with case ordering.  This ensures that the casereader returned by
+       sort_execute now has the same dimensions as the casereader passed 
+       in.
