Generalized modified least squares in the univariate linear model
首发时间:2009-10-21
Abstract:In this short paper, we mainly aim to appeal to readers to pay close attention to the criterion of modified least squares and develop it to generalized modified least squares. The closed-form of the generalized modified least squares estimators for the intercept and the slope are derived. The results are illustrated by a numerical example. The illustration shows that generalized modified least squares is an adjusting criterion such that the resulting fitted line can be sensitive or insensitive to those outlying data values.
