摘要

In questo lavoro l'Autore propone l'impiego di coefficienti di varianza locale e l'utilizzo di matrici di covarianza composte con tali coefficienti per la definizione del possibile intervallo per gli errori casuali. Questo processo gioca un ruolo importante nella stima robusta. Le considerazioni teoriche sono supportate da un esempio di rete (ideale) di livellazione.%In this paper the Author proposes the usage of local variance coefficients and the usage of covariance matrixes originated with their contribution, for the appointing borders of possible interval defined for the random measurement errors. This process plays important role in the robust estimation. During this procedure decisions are made whether the measurement errors can be treated as random or can be suspected of contamination by gross errors. The theoretical considerations are supported by the example of empirical usage of the theoretical levelling network.
