Significados de base estimator en inglés

As an alternative, we introduce a model-assisted approach, resulting in a design- based estimator leveraging a working network model.

The estimator is unbiased and is much more efficient than the variance- based estimator under the single-step stepwise mutation model.

It also has smaller bias and mean square error (MSE) than the variance- based estimator when the mutation follows the multistep generalized stepwise mutation model.
