if I sample from a normal distribution with something like
and add an outlier with
visually shows the point 4 as an outlier
and calculating the probablity of a value of 4 or bigger in 100 samples of norm(0,1)
If I have more than 1 sample above outlier threshold the math is a bit more complicated
My questions are
1) are there better ways to assess probablity of outliers (ie value(s) above theshold from a given distribution)?
2) are they implimented in r?
(I checked outlier and extreme in r help and found nothing helpful)
