Is the Shapiro-Wilk statistic computed with the Royston test even for n<=50?
My company has limited JMP licenses, so I need to make a tool for non-JMP users that produces the same W statistic as JMP for small datasets (<=50 points). The tool I produced by following the Shapiro-Wilk algorithm generates exactly the same output as this online tool (which only works for <=50 data points), which is also the same output as this tool up to 50 data points. The second tool switches...
