TLDR
The developed STAS methodology enhances the current free form surface inspection models, which are mostly based on spatial analysis; into spatio-temporal model, which provides capability to predict the whole part deviation based on partial measurement information and consequently reduces measurement cycle time.About:

Time Series Analysis by State Space Methods
James Durbin,Siem Jan Koopman +1 more
TL;DR: This excellent text provides a comprehensive treatment of the state space approach to time series analysis, where observations are regarded as made up of distinct components such as trend, seasonal, regression elements and disturbence terms, each of which is modelled separately.
