The best linear unbiased estimator BLUE (CXb) of a linear transform CX b in the general Gauss-Markov model (y, E (y) = X b Cov (y) =a2v) is the linear transform C BLUE (Xb) of the best linear unbiased estimator BLUE (Xb) of Xb. Similarly, for the ordinary least squares estimator OLSE (CXb) = C...

The size of the effect of the difference in two groups with respect to a variable of interest may be estimated by the classical Cohen’s d . A recently proposed generalized estimator allows conditioning on further independent variables within the framework of a linear regression model. In this...
