Doubly censored
WebMar 23, 2007 · Since more patients will be censored when θ A = 1.6 or θ A = 1.2 than when θ A = 0.625 = 1/1.6 or θ A = 0.833 = 1/1.2 respectively, the power of the test is smaller in the former scenario for both procedures. Compared with complete randomization, the result shows that the parametric method is more powerful and randomizes more patients to ... Webregression with doubly censored data. Here we point out that a modification of their proposal leads to a multiple imputation approach, where the double censoring is reduced to single censoring by imputing for the censored initiating times. For each imputed data set one can take advantage of many existing techniques and software for singly ...
