FIR-4 order	12.941%	14.061%	17.120%	17.966%	18.090%	20.801%

The performance measure for the estimated femoral AP data $\text{MAPE}$ (3.2) was used to evaluate the cardiovascular system at variant noise for three methods (FIR-2 order and FIR-4 order and Stochastic Calculus). ${\text{MAPE}}_{\text{0.0}}$ is the mean absolute percent error with free noise of the estimated central AP waveform. ${\text{MAPE}}_{\text{0.012}}$ is the mean absolute percent error of the estimate with noise variance = 0.012, ${\text{MAPE}}_{\text{0.024}}$ with noise variance = 0.024, and so forth.
