Consistency index formula.
Estimators. A consistent estimator is one for which, when the estimate is considered as a random variable indexed by the number n of items in the data set, as n increases the estimates converge in probability to the value that the estimator is designed to estimate.. An estimator that has Fisher consistency is one for which, if the estimator were applied to …
