I'm working on an app that monitors a production process, and I've been asked to calculate Cpk and Ppk. I'd never heard of these so I found an explanation
here. Now, I had one semester of algebra and one of geometry. Just looking at these formulas makes me quesy. I can't even read them, much less even begin to write the equivalent code.
So my quest is to find a library that will provide the required methods. No luck with apache.commons.Math. I found a Monarch Charts and SPC Control Chart, but they are commercial products and I know without asking that the company will not purchase it.
I also looked at
JMathLib, a free clone of Matlab, but it also lacks the capability I need.
So, two part question. Does anyone know of a free (or cheap)
Java library that will calculate these statistics? If not, is there some generous soul on here who has traveled this road already and can share some code?
