12         * predict.c: New file. pspp_linreg_predict() uses a linear model
13         to return a predicted value of the dependent variable.
14
15         * coefficient.c: Added pspp_linreg_coeff_get_est() and
16         pspp_linreg_coeff_get_std_err() to access estimated values of
17         coefficients and standard errors.
