In this paper we analyse the problem of the modelling of individual transitions in presence of an incomplete sampling scheme.

In addition to showing the connection between parallel contingent and noncontingent risk comparison problems, we articulate a method for solving both kinds of problems using the "basis" approach. The basis approach has often been used implicitly, but we argue that there is value to making its...
