+
+       * linreg.c (pspp_linreg): Accept a struct design_matrix.  Use new
+       accessor functions pspp_coeff_get_mean, pspp_coeff_get_sd.  New
+       functions pspp_linreg_get_indep_variable_mean,
+       pspp_linreg_set_indep_variable_mean,
+       pspp_linreg_get_indep_variable_sd,
+       pspp_linreg_set_indep_variable_sd. Altered pspp_linreg_get_coeff
+       to use accessor function pspp_coeff_var_to_coeff.
+
+       * coefficient.c: New functions pspp_coeff_get_mean,
+       pspp_coeff_set_mean, pspp_coeff_get_sd, pspp_coeff_set_sd,
+       pspp_coeff_var_to_coeff. Added doubles to hold mean and standard
+       deviation in struct varinfo.

+
+       * linreg/: moved linreg.[ch] to src/math.

+
+       Patch #6512.
+
+       * moments.c (calc_moments): Use gsl_finite instead of finite, as a
+       stopgap measure for portability until appropriate gnulib modules
+       are available.

+
+       * coefficient.c (pspp_linreg_get_coeff): Removed use of
+       coefficient 0 as intercept.
+
+2008-03-01  Jason Stover  <jhs@math.gcsu.edu>
+
+       * coefficient.c (pspp_coeff_init): Ensure first arg is not a null
+       pointer.
+
+       * coefficient.c (pspp_linreg_get_coeff): Make sure we don't return
+       a result beyond the last coefficient, or start with a coefficient
+       beyond the last one if there is only one.

+
+       Adapt case sources, sinks, and clients of procedure code to the
+       new infrastructure.
+
+       * automake.mk: Add new files.
+       
+       * levene.c: Adapt to new casereaders.  Abstract better.
+
+       * merge.c: New file.
+
+       * merge.h: New file.
+
+       * sort.c: Rewrite in terms of case_ordering, merger.
