(a) Left panel shows sample ECG trace with 500 sample points; middle panel shows the MSE for various length time series across several scaling factors; right panel shows normalized MSE (for scale factors τ = 1–10) and SE; (b) top row shows sinusoidal wave with white noise, (c) pink noise, and (d) brown noise; (b) bottom row shows normalized MSE (for scale factors τ = 1–10) and SE for sinusoidal wave with white noise, (c) pink noise, and (d) brown noise, respectively.
