Vibration Signal Forecasting on Rotating Machinery by means of Signal Decomposition and Neurofuzzy Modeling

Table 4

Performance of the statistical error metrics applied to the combination of all model outputs. Also, the performance of the forecasting without the frequency decomposition is also shown in the table.
