Deming vs Passing Bablok at 3 x 3 digits precision

Three digits one

Here the result of a successful simulation with 400 replicas per point at 3x3 digits precision. Classical PaBa still shows a pretty high asymmetry with r.s.e of over 4%. PBequi is performing better, but shows some bias compared to classical Deming methods with an r.s.e over 2%. Quite surprisingly PBequi with jackknife CI performs better that the analytical version with approx. 1.36% r.s.e.

Table of r.s.e. at 3x3 digits precision

Below is also reported a plot for the M- and MM-Deming methods. M-Deming is very well performing, in line with other classical Deming regressions with a r.s.e% of approx. 1.52%. MM-Deming is confirming its bias with an r.s.e% of 2.28%.

Worth noting that the Deming JE/MD method has an r.s.e% of only 0.62%. This method seems much more powerful that the traditional ones and also shows a good symmetry.
