To asses the sensitivity of conclusions to model choices in the context
of selection models for nonrandom dropout, one can oppose the different missing
mechanisms to each other; e.g. by the likelihood ratio tests. The finite sample
behavior of the null distribution and the power of the likelihood ratio test is
studied under a variety of missingness mechanisms.
