The first serverside function called by ds.lexis. This is an aggregate function which identfies the maximum surival time in each study. Adds a random increment to that maximum (to protect against disclosure) and then passes these maxima back to ds.lexis. ds.lexis then identifies the maximum of the maxima and this allows a coherent common set of time intervals to be set across all studies when the collapsed dataframe is expanded by lexisDS2, usually in preparing for a piecewise exponential regression. For more details see the extensive header for ds.lexis.
