Hi Bev D, the link in your post does not work. "page not found"
Welcome to the Cove. Are you referring to post#4 by Steve?

I have some work on SPC posted at - DEAD LINK REMOVED.

Steve had moved most of his works to another address, let's wait for him to update us.

hi, i am currently doing background research on appropriate statistical methods to set up an alert/warning limit to prompt if a process is near the spec limit, could anyone point me in the direction of suitable methods and tools. thanks
I tend to take a totally different approach then those mentioned, as the focus of most SPC charts is around the mean response. I set my action and alert limits based on tolerance intervals and the distribution of individual values. For example, I will set my alert limits based on a 95% confidence and 95% coverage interval and action on 95% confidence and 99% coverage. Both the confidence and coverage can be changed to reflect the risk profile.
