This is an attempt to study two generalized families of estimators of regression coefficients from the literature in the linear regression model under exact linear constraints of parameter vector when the criterion of choice of estimators is taken to be concentration probability of estimator around the true parameter. Following small sigma asymptotic approach, the sampling distributions and the concentration probabilities of two generalised families of estimators or derive and the efficiency of two families is discused with respect to criterion of concentration probability.
