interval scale
3.Bayesian-point and-interval estimations of the scale and shape parameters and the achieved MTBF of the system are obtained.
7.When the patient was optimally sedated (Ramsay scale 2-5 scores), the corresponding median BIS 95% confident interval (CI) were 61-84. The sensitivity and Youden index of BIS value with optimal or under sedation were the highest when BIS=81. The 95% CI of median BIS were 48-58 when Ramsay scale was 6 scores.
