Measurement Systems Analysis allows us to ensure that the variation in our measurement is minimal compared to the variation in our process.
Process Performance (Pp, Ppk) helps determine if your new process is acceptable by measuring ratios of distribution to spread and centering.
Cp and Cpk are considered short-term potential process capability measures for a process. We want to describe this quality in terms of sigma.
Canonical correlation analysis seeks the best sets of linear combinations with independent variables related to dependent variables.
You use non-parametric hypothesis tests when you don’t know, can’t assume, and can’t identify what kind of distribution your have.
