You can see that the New Drug displays better survival probabilities over time than Old Drug or Placebo. You can easily convert this table to a table of Kaplan-Meier failure estimates by replacing survprob = survival with survprob = failure in Program 5.7. [Pg.184]

Sometimes, these data are presented in a shorter table that displays only those time points at which an individual had an event or was censored, and thus the only values of time for which the probability of survival changes. It is more common, however, to see analyses of this type displayed graphically. The Kaplan-Meier estimate of the survival distribution is displayed for both groups in Figure 8.3. The survival curves displayed in the figure are termed "step functions" because of their appearance. We return to the interpretation of Figure 8.3 after we have fully specified the survival distribution function. [Pg.111]

Each scenario comprises a mixture of missions in different environments. The extended Kaplan-Meier approach was used to estimate the probability of survival for each mission. The prohahihty of surviving a scenario was calculated hy simply using the joint probability expression. Results for the probability of loss for each scenario, using the optimistic and the pessimistic risk models, are summarized in Table 3. [Pg.1177]
