Dear Sir,
I have data, coming from tests, consisting of 300 values. Is there a
way in
R with which I can confirm this data to 68-95-99.8 rule or three-
sigma rule?
Can you describe this rule? I get the idea that it might be "private
language" adopted by the SigxSigma sect.
I need to look around percentile ranks and prediction intervals for
this
data. I, however, used SixSigma package and used ss.ci() function,
which
produced 95% confidence intervals. I still am not certain about
percentile
ranks conforming to 68-95-99.7 rule for this data.
The quantile function is pretty much "standard operating procedure".
fivenum will return the values that would appear in a box-and-whiskers
plot.
