FEATURES ![]() Once the data of the time series are loaded in ITTSAE-TSA, user can view the following estimated function from the time series: autocorrelation, partial autocorrelation and cross correlation. Besides, user can differentiate the time series to eliminate its non-stationary behaviour. User must analyse the graphical representation of the selected time series and its autocorrelation and partial autocorrelation function to establish whether the time series presents an non-stationary behaviour and must be differentiated, and infer the type of stochastic process that has generated the time series. User can also analyse the cross correlation function between two of the loaded series to establish whether these signals are uncorrelated or cross correlated. The main features of ITTSAE-TSA are its simplicity, ease of use and interactive nature. Any action carried out on the screen is immediately reflected on all the graphs generated and displayed by the tool. This allows the user to visually perceive the effects of his or her actions. ITTSAE-TSA has been developed with SYSQUAKE 5.0 by José Manuel Díaz Martínez (UNED-DIA), Sebastián Dormido Bencomo (UNED-DIA) and Daniel E. Rivera (ASU-CSEL). |
