Random effects and level 1 censoring
...for (in this case, right) censored results. Within (for example) an R environment, this is easy to do and gives the same solution as survreg even if it is a little heavy. But where there is an hierarchical situation, we need to consider the contributions at level 2. y_ij=X_ij.beta'+err2_i+err1_ij If all the units at level 1 for a given level 2 are censored, then the information we have for the level 2 is itself censored and we should presumably use the survivor function. Conversely if none of the units at level 1 are censored, then the information at level 2 is complete and the density sh...
