Professor Sreenivasa Rao Jammalamadaka from the Department of Applied Probability and Statistics at the University of California, Santa Barbara will be the featured speaker at a Department of Mathematical Sciences statistics seminar. The title of his talk is "Middle-Censoring."
In connection with survival analysis and related problem, there is considerable literature which treats data that is censored from the left, the right or both. In this talk, he considers situations where the data becomes unobservable if it falls inside a random interval in the middle, which is called middle-censoring. This happens in clinical trials and lifetime studies where a subject is temporarily absent or withdrawn from the study and the event of interest occurs during this period, so that the exact time of occurrence cannot be observed.
