Great! Please tell Jay this is excellent. I just wish I had some more information on the interpretation of the statistical analysis results. Jay seems to think we know as much as he does on what Anderson Darling means, ANOVA two factor with vs without replication shows and how to choose between them, and when Levene's are appropriate. It would be really helpful for us mear mortals to better understand which results to select based on what we are trying to learn. I am not saying he has to write a course on statistics, but some enlightenment on interpretation would be very helpful. Respectfully, a statistical mear mortal!
