Graphs of the beta 2 (B2) series: (a) the time function graph of the S1 B2 series values; (b) the time function graph of the S2 B2 series values; (c) the time function graph of the tendency (trend) and of the model of S2 B2 series; (d) the time function graph of the S3 B2 series values. MAPE: the mean absolute percent error; MAD: the mean absolute deviation; MSD: the mean square deviation.
