In Table 1, Eq.(1) shows the CMC for evaluation of the repeatability of waveforms within a test session, while Eq.(4) shows the CMC for evaluation of the similarity of waveforms between test sessions. When the waveforms are
similar, Ra in Eq.(1) and (4) is nearly equal to 1.
If the waveform is dissimilar , Ra is nearly equal to zero.
Eq. was used to evaluated the repeatability of waveforms within each test session as intra-subject reliability. test-retest and inter-tester reliability were evaluated using Eq.
That is to say , Eq. was used for the repeatability between different testers' test session in same day as well as the repeatability between same tester's sessions in defferent test say.
