Leverage Point Identification Method for LAV-Based State Estimation

In this article we enunciate and rigorously demonstrate a new lemma which, based on previously proposed theorem, proves the identifiability of leverage points in state estimation with specific reference to least absolute value (LAV) estimator. context, also propose an algorithm for point identification LAV estimators whose performance is validated by means extensive numerical simulations compared against well-known approach projection statistics (PS). The obtained results confirm that method outperforms PS represents significant enhancement LAV-based as it correctly identifies all measurement set.
