The method is based on pattern recognition and data analysis algorithms. Principal component analysis (PCA) is employed to reduce the complexity of the data to two and three dimensions. PCA involves a mathematical procedure that transforms a number of variables, which may be correlated, into a smaller set of uncorrelated variables called \u2018principal components\u2019. In order to improve the results obtained, the signal was filtered. The filtering was carried out employing a state\u2013space system model, estimated by maximum likelihood with the help of the well\u2010known recursive algorithms such as Kalman filter and fixed interval smoothing. The models explored in this paper to analyse system data lie within the so\u2010called unobserved components class of models.
