Process capability analysis in the presence of autocorrelation |
|
| Authors: | R. Noorossana |
| Abstract: | Process capability analysis when observations are autocorrelated is addressed using time series modelling and regression analysis. Through the use of a numerical example, it is shown that the variance estimate obtained from the original data is no longer an appropriate estimate to be considered for conducting process capability analyses.
