Thus, the GMM estimator can be written as Asymptotic normality is a useful property, as it allows us to construct confidence bands for the estimator, and conduct different tests.
Before we can make a statement about the asymptotic distribution of the GMM estimator, we need to define two auxiliary matrices: So far we have said nothing about the choice of matrix W, except that it must be positive semi-definite.
Based on the baseline GMM constructed by features of Lamb wave signals in structural health state, an on-line continuous updating GMM is studied to learn the dynamic changes of Lamb wave monitoring signals without any prior knowledge of damage patterns.
