Questions regarding Dialysis study
Fragment of a discussion from Course talk:STAT 550 2013
1. There are so many missing data here, which is likely to result in bias in estimation if just getting rid of them. So how can we deal with such a great deal of missing data?
2. In this case, is it necessary to consider clustering effect? How to estimate interclass correlation coefficient?
3. How to decide sample size here since no information about power and effetive size has been provided?
