TLDR
The Modal Assurance Criterion (MAC) as discussed by the authors is a statistical indicator that is most sensitive to large differences and relatively insensitive to small differences in the mode shapes, which can only indicate consistency and does not indicate validity or orthogonality.About:

Model validation: Correlation for updating
TL;DR: A review is presented of the various methods available for the purpose of performing a systematic comparison and correlation between two sets of vibration data and the application of interest is in conducting this correlation process as a prelude to model correction or updating activity.
