In probability, events can be treated just like sets, which means we can combine them using set operations like union, intersection, and complement. Union of Events The union of two events, can be written asE∪ F. Either event happens, or both happen. So, for example, ifE1is the event...
What’s New in PASS 2025? Go to the Online Store We are pleased to announce the release of PASS 2025. PASS 2025 adds 37 new sample size procedures and includes a variety of enhancements. The new procedures include those for Logrank-type tests (8), the ratio of two recurrent event rates...
In probability theory the notion of a set plays a more fundamental role. Furthermore we are interested in very general kinds of sets as well as specific concrete ones. To begin with the latter kind, consider the following examples: (a) a bushel of apples; (b) fifty-five cancer p...

probability distributions over \(\varxi \) . for any probability distribution \(f_0 \in \mathcal p(\varxi )\) , \(f_0(a)\) denotes the probability of the event \(\xi \in a\) . to streamline the notation when \(d=1\) , we let \(f_0(t) = f_0((-\infty , t])\)...
And y>t is not a “rare” event which dominates the “rare event” y>tc. Hence the failure rate of SRAM can be estimated as follow: (7)PˆIS,fail(y>tc)=P(y>t)⋅P(y>tc|y>t) The P(y>t) can be estimated by MC. While the P(y>tc|y>t) can be derived to be ...

Long-term survivors in trials with survival endpoints are subjects who will not experience the event of interest. Membership in the class of long-term survivors is unobserved and should be inferred from the data by means of a mixture model. An important question is how large the sample size ...
