That is m(6) = m(i) = 0.5 ^ (1/n) for i = n = m(i) = 0.5 ^ (1/6) = 0.8909. It results in a smoother line for your example.

The more closer to 1 the more the actual values are normal distributed.Karim Achaibouhttps://www.blogger.com/profile/00372871320913341086noreply@blogger.comtag:blogger.com,1999:blog-3568555666281177719.post-76584465554879403052012-11-06T09:58:15.600-08:002012-11-06T09:58:15.600-08:00I found the first method of creating the normal pr...I found the first method of creating the normal probability plot helpful. But when I use the data from the second method for the first, the corresponding correlations do not agree. It looks like it is because of an error in the expression for m(n). You use 0.5(1/n) when it should be 0.5 to the 1/n power. When I make this change the correlations are close.Steve Eastmannoreply@blogger.comtag:blogger.com,1999:blog-3568555666281177719.post-38808343571163348802012-10-25T22:41:01.290-07:002012-10-25T22:41:01.290-07:00This was of very timely help.

You get them as follows: start with 1/(2*n), so 1/(2*7), then add 2/2n to the previous value. You'll get 1/14, 3/14, 5/14, etc.<br /><br />As the author said, there's a 1/7th distance between each probability value, or 1/n in general.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3568555666281177719.post-57412970051994234202011-02-16T09:30:31.246-08:002011-02-16T09:30:31.246-08:00Where are you getting 1/14, 3/14, 5/14 ... for CDF...Where are you getting 1/14, 3/14, 5/14 ... for CDF at each sample point in the first Normal Plat example?Anonymousnoreply@blogger.com
