It already does support one-pass moments: use the moments1_* functions instead of the moments_* functions. > Second question: moments.c could also be made to compute correlations > between variables in a single data pass.

Is there a logical or computational reason why correlations should be integrated into moments instead of being a separate module? -- Ben Pfaff http://benpfaff.org _______________________________________________ pspp-dev mailing list [email protected] http://lists.gnu.org/mailman/listinfo/pspp-dev
