Improved Confidence Interval Estimation for Oscillometric Blood Pressure Measurement by Combining Bootstrap-After-Jackknife Function with Non-Gaussian Models

Table 1

Comparison of average results (85 subjects with five measurements) with respect to the upper limit and lower limit of CIs (95%) for SBP and DBP using the MAA with Student’s -distribution (MAAST) [7], MAA with GUM (MAAGUM), PMAE, PMAEBG, PMAEBL, and PMAEBC, where is a standard deviation and GUM is the guide to the expression of uncertainty in measurement (GUM) [22].
