+       * predict.c (pspp_linreg_predict): Do something sensible even with
+       bad input.

+
+       * predict.c (pspp_linreg_predict): Improved handling of null
+       pointer args.
+
+       * predict.c (pspp_linreg_residuals): New function.
+
+       * coefficient.c: Improved handling of null pointer args.

+
+       * predict.c: New file. pspp_linreg_predict() uses a linear model
+       to return a predicted value of the dependent variable.
+
+       * coefficient.c: Added pspp_linreg_coeff_get_est() and
+       pspp_linreg_coeff_get_std_err() to access estimated values of
+       coefficients and standard errors.

        * coefficient.c: Added pspp_linreg_get_coeff() to find a
-       coefficient corresponding to a variabl/value combination.
+       coefficient corresponding to a variable/value combination.
