Efficiency (statistics) - Wikipedia

Estimators. The efficiency of an unbiased estimator, T, of a parameter θ is defined as () = / ()where () is the Fisher information of the sample. Thus e(T) is the minimum possible variance for an unbiased estimator divided by its actual variance.The Cramér–Rao bound can be used to prove that e(T) ≤ 1.. Efficient estimators

The investigation has demonstrated that the grinding capacity of a mill is maintained when balls are replaced by pebbles, up to about 30% of the charge volume. The energy dissipation and the surface area for grinding are reduced as the pebble volume increases, and it reasonable to assume that the pebble wear compensates for these changes.
