Regression parameter values for the linear regression log(Y) = p1∙log(X) + p0 between log transformed LF/HF ratios for IBI series with distorted/removed beats (Y) and undistorted series (X) by the RPD, LSP and FFT methods. The distortion rate was 10%. ‘dis’ denotes series with distorted beats and ‘rem’ denotes series with removed beats.
