	* 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.

2006-04-03  Jason Stover  <jhs@math.gcsu.edu>

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