fuzzy observations & sublevels #29
Description
In some data we received, the involvement is not always reported per level, but sometimes it is reported for a group of levels. For example, a pathology report might state that there have been metastases found in a tissue sample taken from the levels III and IV. From a probabilistic standpoint, this is easy to deal with as it means that LNL III or IV are involved and we can simply marginalize over the respective diagnoses.
The problem now lies with the implementation. I think it would be important to add this possibility of reporting "fuzzy" involvement also for the cases where we don't have detailed sub-level reports (e.g. level IIa & IIb). But the implementation should be consistent and comprehensible.
