SI95 is an 'industry standard' speed index for the various listed microprocessors? 2. You derived relative NPS estimates from using relative SI95 figures, pegged to a nominal NPS for one of the processors listed? 3. Where do you get the PLY figure from? (i.e. how did you calculate it--I assume you calculated it somehow) 5. How did you calculate the estimated rating for each line (processor/speed combination)? 4. Is there some sort of auto-correlation or accidental correlation at work in this table? 5. What did you run the regression analysis with? (EXCEL built-in regression tool, or custom-programmed regression method--perhaps via iterative macro loops, etc?) Thanks, --Steve
