The biased estimation problem in free net adjustment model is considered when linear dependence and multicollinearity among the columns of the coefficient matrix exist simultaneously. A class of biased estimators are defined by introducing the canonical form of the rank deficient Gauss Markov model. The feature of our approach is to reduce the biased estimation problem in the rank deficient Gauss Markov model to the one in the rank full Gauss Markov model.

The biased estimation problem in free net adjustment model is considered when linear dependence and multicollinearity among the columns of the coefficient matrix exist simultaneously. A class of biased estimators are defined by introducing the canonical form of the rank deficient Gauss Markov model. The feature of our approach is to reduce the biased estimation problem in the rank deficient Gauss Markov model to the one in the rank full Gauss Markov model. Some important properties are discussed. As special cases of our class, seven known biased estimators are extended to the rank deficient Gauss Markov model, where the optimal values of the biasing parameters are determinated through the rank full canonical model. At last, a numerical example is presented.
