Two Cobas-Bio analyzers were found to have significantly increased imprecision, owing to absorbance errors, when we used rotors pieced together from segments of four to 10 cuvets. The difference in CV between whole/unbroken and four-cuvet or 10-cuvet segment rotors was significant by Student's unpaired t-test (P = 0.038 and less than 0.0001, respectively) and by the Mann-Whitney U test (P less ...

We consider the problem of comparing sojourn time distributions of a transient state in a general multistate system in two samples (groups) when the transition times are right censored. Using the reweighting principle, a two-sample Mann– Whitney type of U -statistic is constructed that compares only the uncensored sojourn times from the two distributions. A second Mann–Whitney type of statistic...
