Hi, My name if Frank Tappen and I work for an SPC Software Company called DQS. A customer of ours has asked us to create Pearson Curves of their non-normal data sets and to calculate several statistics; one of them being CPK. I am searching for statistical routine which can do this for us and came across "R". My question is, does "R" have the capability of calculating CPK for non-normal distributions, in particular Pearson curves? Sincerely, Frank J. Tappen -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
