46、. This class of designs minimizes the variance of the regression coefficients (and thus translates to a higher degree of confidence in the estimated function). A first order design that is orthogonal is the 2k design, where there are no cross-product terms and no aliasing.In moving to ...
Consequently, AL are calculated in this paper based on the model prediction at process target condition plus-minus three-times the model’s standard deviation, represented by the RMSE. However, due to the limited number of experiments in the initial phase of the LDoE, a four SD approach was...
In this study, the process capability analyses presented in [17] are applied to a papermaking process. Figure 1, is shown the proposed method called the “non-invasive method to evaluate the fuzzy process capability indices” (Non-I FPCA). Figure 1. A non-invasive method to evaluate fuzzy...
