Three sigma rule
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?
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.
Thanks and regards,
Salil Sharma

Performing gage R&R study in R w/more than 2 factors
...on that lets
you include up to eight additional factors besides the usual two that
are present in gage studies (parts and operators). If I wanted to
include n additional random factors, is there a package or built-in
functionality that will allow me to do that?
I've been experimenting with the SixSigma package, and that has a ss.rr
method which works great---as long as your experiment only contains two
factors. I've also been using lmer from lme4 to fit a linear model of my
experiment, but the standard deviations generated by lmer don't match
what I'm seeing in Minitab. Since all my f...

Variability plot in R
Is there a package in R that can do a variability plot?
A variability plot is a kind of categorized dot plot. (If there is a lot of data in each category, box plots are used rather than dot plots.)
Usually, the categories are factor level combinations. All the dot plots appear in the same window; below the x-axis a hierarchy of factors
shows which dot plot corresponds to which factor-level
