- looks like an early chance to test them. If you go back and there is *not* any problem, then here's a hint that your limits may not be useful after all. I suppose, if you *know* you did badly, you could write yourself a failing grade -- based on guilt-feelings rather than on data -- and change the limits without ever testing whether there is a real problem. -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at http://jse.stat.ncsu.edu/ =================================================================
