Polynomial errors-in-variables regression model under a mixture of classical and Berkson errors is studied. We construct strongly consistent estimators for unknown parameters and show that under mild conditions the estimators are asymptotically normal with a nonsingular asymptotic covariance matrix. Moreover, we find two pairs of asymptotically independent estimators. A numerical example is provided to demonstrate that even under the normality assumption there are no more asymptotically independent pairs.
