无偏估计

Secondly, in this study, China's staple food demand is offered to have both long-term and short-term stability, and it fits the "best linear unbiased estimator", goodness of fit , hence it is predictable and has long-term developing co-relation--the rise of food consumption causes the rise of food price and the increase of food consumption stimulate the increase of income.
