Development of New Robust Optimal Score Function for the Weibull Distributed Error Term in Multilevel Models

A popular robust estimation technique for linear models is the rank-based method as an alternative to the ordinary least square (OLS) and restricted maximum likelihood (REML) in the presence of extreme observations. This method is applied in machine reliability analysis and quantum engineering, espe...
