Expected Deaths

This program calculates the expected number of deaths for a planned study. The program assumes uniform accrual and exponential survival. It allows the user to specify a follow-up period after the close of study accrual. The program default presents a table of results. Alternatively, user can calculate the expected proportion of deaths at a given time, or the time at which a given proportion of deaths have occurred. The program will allow the user to specify a percentage of patients that have no risk ('Cures').
