A semiparametric nonlinear mixed model approach to phase I profile monitoring
Gomaa A.-S.; Birch J.B. ( Taylor and Francis Inc. , 2019 , Article)When process data follow a particular curve in quality control, profile monitoring is suitable and appropriate for assessing process stability. Previous research in profile monitoring focusing on nonlinear parametric (P) ... -
Outlier robust nonlinear mixed model estimation
Williams, J. D.; Birch, J. B.; Abdel-Salam, A.-S. G. ( John Wiley & Sons, Ltd. , 2015 , Article)In standard analyses of data well-modeled by a nonlinear mixed model, an aberrant observation, either within a cluster, or an entire cluster itself, can greatly distort parameter estimates and subsequent standard errors. ...
