On the minimax robustness against correlation and heteroscedasticity of ordinary least squares among generalized least squares estimates of regression

Biometrika
Summary We revisit a result according to which certain functions of covariance matrices are maximized at scalar multiples of the identity matrix. In a statistical context in which such functions measure loss, this says that the least favourable form of dependence is in fact independence, so that a procedure optimal for independent and ...
